Entry-points vgg2-*-with-eval not listed in bob.bio.database group

Some entry-points in pyproject.toml (notably vgg2-short-with-eval and vgg2-full-with-eval) are listed in the entry-points group bob.bio.config but not in bob.bio.database.

This leads to issues and confusion when passing the config to the --database option of bob bio pipeline simple and listing with resources.py.

We should (if it was not omitted for a reason) also add those config entry-points to the bob.bio.database entry-point group.
