TASK: Remove policy for removed fluid widgets

The cr paginate widget was removed see
neos#5425

But as identified here there is still a method privilege to be adjusted:
neos#4478 (comment)

Further long ago this change seems to contain a hiccup introducing a policy for a `LinkRepositoryController` which was NEVER part of the codebase though:

neos@f5053cc#diff-818aacc12f1dbf0bc391a8711ae5a3d56cceb29494b5997dd2a43d793b6dd44eR8

Thus this line was adjusted further.
