George Kalpakas 80f11a9b86 ci: check that there are no unused contributor images (#41290)
When a contributor was removed from `contributors.json`, the
corresponding image should also be removed from
`aio/content/images/bios/`. However, this was often overlooked,
resulting in unused images remaining in `aio/content/images/bios/`.

This commit adds a check to ensure that all images in
`aio/content/images/bios/` are referenced in `contributors.json`.
