✨ Codeberg.org support

### Is your feature request related to a problem? Please describe.

no

### Describe the solution you'd like

Please add support for adding codeberg.org accounts.

### Describe alternatives you've considered

GItHub. But I don't like my code scanned and used for copilot. GitLab is a usability nightmare.

### Additional context

Many open source projects and people moved to codeberg.org after all that GitHub copilot controversy. Supporting these type of accounts make a great commit to this project.
