This is similar to the removed `top-enabled` option but for the Popular feed.
The instance needs to be restarted if the feed was enabled.
Editing admin options on the preferences page is also fixed.
The handling of the feed pages now only happens in a single place.
Instead of redirecting:
- The Top feed now displays a message that it was removed from Invidious.
- The Popular feed now displays a message that it was disabled if it was.
The Top feed used to be a feed based on YouTube ratings. Once YouTube removed
publicly available ratings the Top feed was removed from Invidious but the
option to display a link to it remained.
