Attempt to update to 2.9+

The Ui is working, but the data-base is very old:

I haven't made a pull request, since there are still some errors.
I was thinking, it would be great if it was possible to update the json file somehow automatically by searching and scraping info from github/gitlab etc. to locate the blender add-ons and extract date for update and version number __info__.py etc.
Apparently there are ways to do this: https://python.gotrained.com/search-github-api/ or as a module: https://github.com/janeklb/gh-search Both needs a user inserted tolken(which is annoying). And a scraper module: https://github.com/shobrook/git-pull
I don't know anything about these things, but it would be cool if that registry json file automatically could be updated/stay updated.

If that would work, it would become a fully Blender integrated version of: https://blenderdepot.netlify.app/

Maybe the links from here could be converted to the JSON file? https://github.com/agmmnn/awesome-blender
