Fix `license` metadata

We recently updated the datasets metadata for consistency with other repo types (models & spaces)

Thanks! 🙏

-# Dataset Card for Jhotdraw

-## Dataset Description
-
-- **Paper:** [Helpful or Not? An investigation on the feasibility of identifier splitting via CNN-BiLSTM-CRF](https://ksiresearch.org/seke/seke18paper/seke18paper_167.pdf)
-
-### Dataset Summary
-
-In programming languages, identifiers are tokens (also called symbols) which name language entities.
-Some of the kinds of entities an identifier might denote include variables, types, labels, subroutines, and packages.
-
-Jhotdraw is a dataset for identifier segmentation, i.e. the task of adding spaces between the words on a identifier.
-
-### Languages
-
-- Java
-
-## Dataset Structure
-
-### Data Instances
-
-```
-{
-    "index": 0,
-    "identifier": "abstractconnectorserializeddataversion",
-    "segmentation": "abstract connector serialized data version"
-}
-```
-
-### Data Fields
-
-- `index`: a numerical index.
-- `identifier`: the original identifier.
-- `segmentation`: the gold segmentation for the identifier.
-
-## Dataset Creation
-
-- All hashtag segmentation and identifier splitting datasets on this profile have the same basic fields: `hashtag` and `segmentation` or `identifier` and `segmentation`.
-
-- The only difference between `hashtag` and `segmentation` or between `identifier` and `segmentation` are the whitespace characters. Spell checking, expanding abbreviations or correcting characters to uppercase go into other fields.
-
-- There is always whitespace between an alphanumeric character and a sequence of any special characters ( such as `_` , `:`, `~` ). 
-
-- If there are any annotations for named entity recognition and other token classification tasks, they are given in a `spans` field.
