Stop using SkinTemplateNavigation::SpecialPage and SkinTemplateNavigation hooks will be deprecated and replaced by SkinTemplateNavigation::Universal
See T255319
Looking at these hooks and the other migrations that have happened this should be an easy change.
Seemingly there is only one of these in Wikibase https://gerrit.wikimedia.org/g/mediawiki/extensions/Wikibase/+/df949038c686af9c59b1ea5d554b55c81e338b55/extension-repo.json#922
With an implementation at https://gerrit.wikimedia.org/r/plugins/gitiles/mediawiki/extensions/Wikibase/+/df949038c686af9c59b1ea5d554b55c81e338b55/repo/includes/RepoHooks.php#488
(This should be double checked when picked up)
Acceptance Criteria:🏕️🌟
- The old hooks are no longer used
