Markdown update for -ProgressAction and missing command

[PalmEmanuel]

Contributing a Pull Request

Overview/Summary

Updates markdown documentation to take the new common parameter -ProgressAction into account, and adds markdown help for new command Get-UsedModulesInBicepFile.

Note: Some whitespace is changed around in the parameter blocks because of the fix script I use to manually move the parameter -ProgressAction.

Some files had powershell as the language for the code blocks. If we want to keep that I can go through all of them and add it, but the next time we run the platyPS update in full it's going to overwrite it again.

We added that to make the docs look better on github. But I guess that it's not that common to go there to read it. I can live without the highlighting to simplify managing docs.

Was bored. Tried to catch up with y'alls sudden development adventures yesterday. Fixed the merge conflict 😁
