Add docs/support for other Dex connectors

[stoehdoi]

FEATURE REQUEST?

Dex also supports other connectors besides GitHub and Google. I've tried to use Microsoft Azure AD and it is working fine. Can we add a note that other connectors are supported too or include them in the sample configuration.

This is a working configuration for Microsoft connector

    connectors:
      - type: microsoft
        id: microsoft
        name: Microsoft
        config:
          clientID: # Add your Microsoft Azure Client ID here
          clientSecret: # Add your Microsoft Azure Client Secret here
          redirectURI: http://<NODE_IP>:32000/callback
          tenant: # Add your Microsoft Azure Tenant ID here (if applicable)

Hii.. I'd like to work on this issue.. Can you please mention specifically where is the note supposed to be added and what should be the context of the note?
