There has been no changes related to extensions between 14.0 and 14.1
AFAIK, so that looks like an issue with the extension shipped in
repmgr and its packaging.

If you want to speed up things, one thing you could do is perhaps drop
the extension before the upgrade and re-create it on the new cluster
once you are done with pg_upgrade? It is not uncommon to have
post-upgrade reconfigurations depending on what you are doing. This
one is a bit extreme, and it may not work if that's a packaging
issue..
