build and deploy CI job fails on pass renames (and deletions)

https://github.com/google/heir/actions/runs/19438110758/job/55614288217?pr=2396

In this CI, the job failed because it couldn't find the name of a doctest that existed in a markdown file from the bazel cache. The PR had renamed the pass, so the file was no longer there.

We should detect deletions and renamed of documentation and rebuild as needed
