Update dataset card with metadata, links and usage instructions

Hi, I'm Niels from the Hugging Face community science team.

I'm opening this PR to improve the dataset card for SeeU45. My changes include:
- Adding YAML metadata for `task_categories` (`image-to-video`) and `license` (`cc-by-nc-nd-4.0`).
- Including direct links to the research paper, official project page, and GitHub repository.
- Adding a "Sample Usage" section showing how to download the dataset via the Hugging Face CLI, as documented in the official repository.
- Adding the BibTeX citation for researchers using this data.
