Bumped pyenv version to be able to install newer interpreters

Thanks for the PR.

I didn't think other human beings beside myself found much utility for this github action because most of the PRs I'd seen come from bots.
With that said, I'm wondering if you and @ursetto would like to start a tiny community to maintain this and I'd move the project out of my personal account into a github org.

In the mean time I'll just merge both of your PRs and make a new release.

Thanks!

Sure. Throw together a lightweight org and we can share the trivial maintenance burden in perpetuity

None of this is rocket-science that couldn't be recreated in a workflow but much hat tip to your credit it just works so why bother?

Just bumping the pyenv dep periodically and tagging is perfecto until something changes
