ci: cleanup and pin cibuildwheel

[henryiii]

Cleaning up the file just a bit, mostly pinning cibuildwheel, as version 2.0 will drop Python 2/3.5, which might be a surprise if you just always install the latest version. It looks like you might use dependabot + pinning in actions, so you might like the action form of cibuildwheel better, but it's about to move from joerick/cibuildwheel to pypa/cibuildwheel, so that could be done after the move to pick up the shiny new name. :) Edit: moved, so using action.

So this refactoring doesn't seem to work (yet).

[henryiii]

I thought pipx recognized a version number without having to use --spec. The action doesn't have to worry about that.

[ajfriend]

Awesome! Thanks @henryiii! Would you happen to know if it's similarly easy to extend this to also build for aarch64 and Apple Silicon?

[ajfriend]

But I should also figure out how this overlaps with #183

[henryiii]

It should be pretty easy, depends on if you support Aarch64 (#183) and if there are any dependencies that don't support Apple Silicon yet. I could draft an example PR, possibly.
