Add support on pre-commit manager for other datasources

[rimoley]

Tell us more.

Hi,
currently pre-commit manager is only compatible with `github-tags or gitlab-tags datasources.
Due to availability, we have mirrored precommit hooks repositories in an internal bitbucket, so the proposal would be to allow other datasources like git-tags or bitbucket-tags to have more flexibility on where to looks form tags.

Our workaround for now, is to use a custom regex that tracks the version via github-tags, but this would required to modify all the precommit files in our repos, which it is doable yet inconvenient :)

Thanks :)
Regards
