Add optional redirect from *.visualstudio.com to dev.azure.com/*

[kroeschl]

Microsoft recommends using dev.azure.com/{org} instead of {org}.visualstudio.com: https://learn.microsoft.com/en-us/azure/devops/extend/develop/work-with-urls

It would be nice to automatically redirect from {org}.visualstudio.com because switching between the two can force the user to re-authenticate on both sites, which is annoying.

Having run with this on my local system for a while, at least this implementation doesn't stop the connection soon enough to prevent having to re-authenticate with Azure. I'm not sure if/how we can run sooner though.
