[Discussion] any reason pypi releases don't have tags here?

Noticing releases on pypi for 2.3.1 , 2.3.2 have no tags here in github and there seem to be [only two tags total](https://github.com/deezer/spleeter/tags) despite there being around 30 releases total. I can of course make a good guess how to line up the source here based on dates but any reason tagging isn't applied for each release? usually projects can automate releases using github actions this way, ends up being less work for everyone.
