bug: ADO Pipeline hangs on reporting docs status back

[schristoff]

Describe the bug

ADO Pipeline checks in the first stage if it's a docs only PR - and if it is, it never finishes and just hangs.

To Reproduce

Checkout pipeline on this docs only pr

Expected behavior

Let's update the pipeline to skip all other tests so that we can get that ✅

I attempted to implement a fix for this in #2810 - but it still needs to be manually bypassed. The goal is that if it is a docs-only-pr we get green integration tests so that we can enable auto-merging.
