entrypoint: Restore doc grouping for MediaWikiEntryPoint

Follows-up Ib70e4e67e4cb1.

* This removed index.php from the "entrypoint"
  group, but did not add MediaWikiEntryPoint in its stead.

* Fix broken `@see` reference, leading slash is not part of the
  identifier for the `@file` block index.php, only works without it.

* Move the defgroup to a more natural place in the parent class' file.
