ci: move DI exploration tests to GitLab

[P403n1x87]

We extract the exploration tests from the rest of the framework tests and move them to GitLab. We also pick some different frameworks as well. To begin with, we start with boto3, which at the time of opening this PR is the most downloaded package from PyPI. We also introduce a matrix to ensure that we test the same framework with all the supported versions of Python.
