ubuntu-20.04 is being retired by Github
tar_gz is mainly to verify URLs, OS version doesn't matter

Now that ubuntu-24 is out of beta at Github

Since for ubuntu_build, we only use one OS version
and the changes between versions are not as drastic as with MacOS,
it seems safe to have it upgrade automatically.

Github has finally released those as free and retired macos-11

Actions runner warns about v2 deprecation

Only run tests for subcommands that use the native extension

* CI: Bump OS versions

Github released ubuntu-22.04 and macos-12 from beta
and deprecated ubuntu-18.04 and macos-10.15, due to dropping by 2013.

* CI: clean up installed packages

Now the setup is to add to both rc and profile:
1) set PYENV_ROOT
   (can do it unconditionally -- since if you change it,
   you need to update all places anyway since any of them can be run first)
2) Add `pyenv` to PATH if not already there
3) eval "$(pyenv init -)"

Not a breaking change, old setup will continue to work.

Now that Travis check has been removed from the repo
