[MQ] Make doc updates only trigger the analyze step in CI

[vcolin7]

Currently, changes to files like README, CHANGELOG, CODEOWNERS, or our scripts and YAML files cause pipelines to run builds and tests, which is wasteful and time-consuming. When updating files like the ones mentioned above, we should only run the analyze step of the pipeline which checks things such as spelling, for example.

This would be a nice quality of life improvement.

It might make more sense for @chidozieononiwu to own this one since he has the most knowledge of our readme generation infrastructure
