[stable-6] Lock sanity test versions based on what we were testing when 7.0.0 was released

[tremble]

SUMMARY

Now that stable-6 is primarily security-/bug- fixes only, lock the Ansible/Python versions of the Ansible sanity tests that we run. Explicitly excludes running against the milestone/devel versions of the tests since they're a moving target. While we should be applying these fixes to main/stable-7, many of the fixes are primarily cosmetic in nature and don't warrant backporting all the way into stable-6 and beyond.
