Experimental CI changes

[aMahanna]

Branched from #291

Experimenting with Github Actions & CircleCI to make use of matrices to cover a variety of testing environments

              python_version: ["3.10"] # ["3.8", "3.9", "3.10", "3.11", "3.12"]
              arangodb_config: ["single"] # ["single", "cluster"]
              arangodb_license: ["community"] # ["community", "enterprise"]
              arangodb_version: ["latest"] # ["3.10.10", "3.11.4", "latest"]

1. Updates .circleci/config.yml
2. Renames build.yaml to docs.yaml
3. Updates starter.sh

Uploading coverage to coveralls won't be possible until we request access from the Organization Admin:

Will figure out who that is..

Hopefully we can revisit using cimg/python with starter.sh as that would cut the job times from ~4 minutes to ~2 minutes.

We currently rely on ubuntu-2204 in combination with pyenv, which is a ~2min bottleneck:

For some reason pyenv 2.3.37 does not recognize 3.12 when attempting to do pyenv install 3.12...

However, pyenv install 3.12 worked fine locally with pyenv 2.3.31 🤔

will revisit

Leaving the test job as a reference should we ever need to move back to testing on Github Actions

Average job time here is ~1-2 minutes, but the disadvantage is that we lose access to CircleCI's built-in analytics dashboards

Want to clarify - according to the current state of starter.sh:

community --> docker/arangodb (https://hub.docker.com/r/arangodb/arangodb/tags)
enterprise --> docker/enterprise (https://hub.docker.com/r/arangodb/enterprise/tags)

Perhaps we can revisit the idea of community-preview (https://hub.docker.com/r/arangodb/arangodb-preview/tags) and enterprise-preview (https://hub.docker.com/r/arangodb/enterprise-preview/tags)
