CI improvements

[Zeitsperre]

Overview

ThiS PR adds a few small changes to ensure that commits are used for version control instead of tags.

It also adds a few updates to the docs-building step, relying solely on tox and make for CI purposes (easier to configure).

Finally, recent changes to macos-latest require that non-standard "taps" be approved. This affects coveralls running on macOS insofar as an additional approval step is now required. Hoepfully the Coveralls devs will adjust this soon.

Additional Information

ReadTheDocs is asking that project migrate from the manual OAuth hook method to the new ReadTheDocs App. Sometime last week, manually-configured hooks stopped working globally, so ReadTheDocs needs to be installed in Geopython, at the very least on this project if we want to continue building the docs on PRs and on changes to main.

I've sent a request in that needs to be approved by someone with admin access at geopython. @fmigneault or @cehbrecht, could either of you approve that? I can finish the migration on RTD afterwards.

PR looks fine for the CI part.

@Zeitsperre
I do not have admin access to grant GeoPython access.

@Zeitsperre I have not seen a request ... maybe it goes to @tomkralidis ?

I'll take a look at the ReadTheDocs updates and how they affect other projects.

@tomkralidis Thanks! Please let me know when you've had a look at things.
