Subject: [PATCH] Remove unused rollback module

The mediawiki.page.rollback module was previously introduced in this
patch:

https://gerrit.wikimedia.org/r/c/mediawiki/core/+/242050

However, the change was reverted soon after and this module alongside
its JavaScript were left in the code, even though they are not used and
have been replaced by the mediawiki.page.rollback.confirmation module.

Bug: T218574
