Feat: Add timestamp to nightly release tag and name

This commit updates the nightly release workflow to include a timestamp in the release tag and name.

-   Appends the `NIGHTLY_TIME` environment variable to the `tag_name` and `name` of the release.
-   Updates the release `body` to reflect the `NIGHTLY_TIME`.
- This change makes release names and tags unique over time.
