Data Dictionary - Read more - part II

[NoopDog]

Need

UI updates in Figma to help the scannability of the data dictionary.

1. "Show more" link is removed; instead, we have a "hand" cursor on the whole row, which is shaded on hover. Clicking the row opens and closes the row similar to the Hugging Face table.
2. The "Description" heading only shows when the row is open.
3. "Required" tag is repoisitioned to the right.
