Simplify release process with "release-please" #132
Description
I recently discovered release-please which eases the release process by automating quite a lot of the tasks that we currently do manually. I would be keen to try out this tool and see if it could work for Wikidata-Toolkit, which has a fairly low traffic.
This would require adopting the "conventional commits" style of commit message:
fix:which represents bug fixes, and correlates to a SemVer patch.feat:which represents a new feature, and correlates to a SemVer minor.feat!:, orfix!:,refactor!:, etc., which represent a breaking change (indicated by the !) and will result in a SemVer major.
The migration to this release process would require merging #131, as "release-please" doesn't handle the generation and upload of release artifacts by itself.
