Currently, we have a few environment variables that are used within CLI.
Example: CLIMICROSOFT365_AADAPPID. Since we're moving everything from AAD to Entra, let's do this with our environment vars as well.

Example: let's rename CLIMICROSOFT365_AADAPPID to CLIMICROSOFT365_ENTRAAPPID.

• Let's find all CLI environment variables with AAD and rename them
• Make sure the old (AAD) environment variables are still working
• Replace all old environment variables in the docs with their new name
