Describe the contribution

• Fix Document deployment reusable workflow fails deploy step #465
• Fix Docs not deployed when PR is merged to main #463

Now always running for main branch actions (will deploy on fork if you push main). Also rejecting attempts to deploy and use the cache at the same time since I can't figure out how to make that work (password fails on deploy).

Testing performed
Tested w/ a push of main to my fork at https://github.com/skliper/cFE/actions/runs/2203904971, note that branch also contains updates to deploy locally to avoid the password issue.

Expected behavior changes
Deploy on push to main

System(s) tested on
CI

Additional context
Only caller impact is for cFE that tried to use the cache and reusable deploy. CF and cFS workflows not impacted.
