Incorrect Environment Variables name in main.bicep for GLOBAL_DOCUMENTS

[zedhaque]

Hi,

Found a bug in main.bicep when it comes environment variables.

Currently:
AZURE_ENABLE_GLOBAL_DOCUMENTS

It should be:
AZURE_ENABLE_GLOBAL_DOCUMENTS_ACCESS

This issue is for a: (mark with an x)

- [x] bug report -> please search issues before submitting

By the way did I mention UNAUTHENTICATED_ACCESS is the best feature ever 🥇
I have revert back all my hacks and now back in sync with the repo :D :D
