Github Wikidata Bot Versions Save

The new release classifier accepts many previously unknown versions, catches prereleases much better and got proper automatic testing.

The configuration of the bot is now done in a single file called config.json.

Pipenv, black and logging were added for better code and debugging, "title", "date" and "version type" were added as qualifiers and various bugs were fixed.

Thanks to @Nudin, the number of covered projects could be significantly increased.

See https://xtools.wmflabs.org/ec/wikidata/Github-wiki-bot for details.

See [https://www.wikidata.org/wiki/User_talk:Konstin#Release_date](wikidata talk page] for why this change was necessary

This is technically a bugfix release.
