Have versions on Read the docs

[ao-picterra]

I'm trying to figure out a way to allow people to see docs for old versions (adding a changelog is not enough). Reading [this(https://docs.readthedocs.com/platform/latest/versions.html#managing-your-versions) it looks it should happen automatically but it's not, so before digging in / opening a GH issue I was wondering if someone has a vague idea of why.

On the GH repo, the rtd webhook is only configured to get new tag pushes, but not new release, not sure if that's the issue. Or if we push a new tag now

Seems like the issue is we don't want a "stable" version, we want that version to be named after the tag name. Not sure how to do this

I've updated the repo webhook config to also notify rtd of releases. Let's see if that changes anything for the next one.
