test: fix broken assertions after default provider and URL changes

- Replace bitbucket provider checks with codeberg/gitea (bitbucket was
  removed from default config in favour of codeberg + gitea)
- Update proxy e2e link assertion from /#/push/ to /push/ (changed in
  the push list/detail UI overhaul)
