[llvm] [Github] Add build Flang docs in CI if autogenerated files change (PR #72721)

[Aiden Grossman via llvm-commits]

https://github.com/boomanaiden154 created https://github.com/llvm/llvm-project/pull/72721

Currently, when changes are made to the tablegen files that build the docs, the docs build is not tested. This should rarely cause breakages, but it's cheap to test and there isn't a major reason not to.
