Improve dataset card: Add task categories, update language, add sample usage and acknowledgements

This PR improves the dataset card for VitaBench by:

* **Updating metadata**:
* Adding `task_categories: ['text-generation']` for better discoverability of the benchmark's domain.
* Updating the `language` tag from `zh` to `['zh', 'en']`, as the benchmark and its documentation support both Chinese and English tasks, as indicated by the `vita run` command.
* Adding `benchmark` and `llm-agents` to the `tags` for more precise categorization.
* **Adding comprehensive usage instructions**:
* A new "Sample Usage" section has been added, incorporating the "Quick Start" guide from the GitHub repository. This includes detailed steps for installation, LLM configuration, and running/re-evaluating/viewing evaluations, complete with code snippets.
* The content from the redundant `

-## 🛠️ Environment
+## Sample Usage
 
 VitaBench provides an evaluation framework that supports model evaluations on both single-domain and cross-domain tasks through flexible configuration. For cross-domain evaluation, simply connect multiple domain names with commas—this will automatically merge the environments of the specified domains into a unified environment. Please visit our GitHub repository [vitabench](https://github.com/meituan/vitabench) for more detailed instructions.
 
+### Installation
+
+1. Clone the repository:
+```bash
+git clone https://github.com/meituan/vitabench.git
+cd vitabench
+```
+
+2. Install Vita-Bench
+
+```bash
+pip install -e .
+```
+
+This will enable you to run the `vita` command.
+
+
+### Setup LLM Configurations
+
+If you want to customize the location of the `models.yaml` file, you can specify the environment variable `VITA_MODEL_CONFIG_PATH` (default path from repository root is `src/vita/models.yaml`). For example:
+
+```bash
+export VITA_MODEL_CONFIG_PATH=/path/to/your/model/configuration
+```
+
+Example `models.yaml` file
+
+```yaml
+default:
+  base_url: <base url>
+  temperature: <temperature>
+  max_input_tokens: <max input tokens>
+  headers:
+    Accept: "*/*"
+    Accept-Encoding: "gzip, deflate, br"
+    Content-Type: "application/json"
+    Authorization: "Bearer <api key>"
+    Connection: "keep-alive"
+    Cookie: <cookie>
+    User-Agent: <user agent>
+
+models:
+  - name: <model name>
+    max_tokens: <max completion tokens (for some models, use max_completion_tokens)>
+    max_input_tokens: <max input tokens>
+    reasoning_effort: "high"
+    thinking: 
+      type: "enabled"
+      budget_tokens: <budget tokens>
+    cost_1m_token_dollar:
+      prompt_price: <dollars per 1 million tokens>
+      completion_price: <dollars per 1 million tokens>
+```
+The default configuration can apply to all models, the custom model configuration can overwrite default values.
+
+### Run evaluations
+
+To run a test evaluation:
+
+```bash
+vita run \
+  --domain <domain> \              # support single domain (delivery/instore/ota) and cross domain ([delivery,instore,ota])
+  --user-llm <model name> \        # model name in models.yaml
+  --agent-llm <model name> \       # model name in models.yaml
+  --enable-think \                 # Enable think mode for the agent. Default is False.
+  --evaluator-llm <model name> \   # The LLM to use for evaluation.
+  --num-trials 1 \                 # (Optional) The number of times each task is run. Default is 1.
+  --num-tasks 1 \                  # (Optional) The number of tasks to run. Default is the number of all tasks.
+  --task-ids 1 \                   # (Optional) Run only the tasks with the given IDs. Default is run all tasks.
+  --max-steps 300 \                # (Optional) The maximum number of steps to run the simulation. Default is 300.
+  --max-concurrency 1 \            # (Optional) The maximum number of concurrent simulations to run. Default is 1.
+  --csv-output <csv path> \        # (Optional) Path to CSV file to append results.
+  --language <chinese/english> \   # (Optional) The language to use for prompts and tasks. Choices: chinese, english. Default is chinese.
+```
+
+Results will be saved in `data/simulations/`.
+
+### Re-evaluation simulation
+
+Re-evaluate the simulation instead of running new ones.
+```bash
+vita run \
+  --re-evaluate-file <simulation file path> \
+  --evaluation-type <evaluation type> \
+  --evaluator-llm <evaluation model> \
+  --save-to <new simulation file path>
+```
+
+### Viewing Results
+```bash
+vita view \
+--file <simulation file path> # If provided, only view the given simulation
+```
