Add deepin 23 repositories

[wineee]

• rename old deepin to deepin 20
• use deepin instead of Deepin (when using deepin as a standalone branding name, the first letter needs to be in lower-case)
• add repositories(main, community, commercial) for deepin 23

New repository submissions are required to provide links to package sources.

commercial (non-free) packages can not provide package sources, how to exclude it

Any progress for this? @AMDmi3

Hopefully I'll get to it in January. This requires testing on staging repology instance I'm not able to run right now.

Please provide examples. Don't these still have package recipes at least?

deepin is not officially provided any package recipes website

As far as I can see, nvidia is the only package in commercial, and there even is a repository (though it's empty). If there are no/almost no other packages which generate links to nonexisting or empty repositories I'm fine with that.
