Synchronize with `git` providers

[shuvashish76]

Feature request to support sync data with git providers e.g. GitHub, GitLab, Codeberg, Gitea, SourceHut etc.

For example see:

• https://f-droid.org/en/packages/org.stridetasks.stride/
• https://f-droid.org/en/packages/org.handmadeideas.floccus/

Something similar is already requested in #5 but this specific is only for supporting git providers.
