Dev Home GitHub Extension: More GitHub instance type support needed & more information needed to help people sign-in correctly

[JustinGOSSES]

Suggested new feature or improvement

(1) Need to be able to sign into GitHub EMU and GitHub Enterprise Server and get data into DevHome.
(2) Developers need to be able to see repository information organized by GitHub instance type & accounts.
(3) It needs to be very clear what username is being used to sign-in as the current approach merely opens the default browser and whatever GitHub account was last active there will be what is signed into. If a sign-in has already occurred in recent past, the browser seems to skip the page that tells you what instance and account you are signing into. It merely says "you are signed in and can go back to DevHome". This occurs even if you have already signed out on DevHome side. This leads to a confusing user experience. It would be helpful to have more information related to this BOTH before clicking "sign-in" and after "sign-in" is complete. Perhaps a "how to sign-in to multiple accounts or instances" helper information at a link?

Scenario

It is common for people in an enterprise to have multiple GitHub accounts for different instances of GitHub or even different users for the same instance in less common situations. Instances can include GitHub public, GitHub EMU, GitHub Server, etc. In some cases, the same username might be used across different instances but different login URLs.

Given developers work occurs across these instances, all should be supported and it should be clear where each repository issue or PR notification comes from.

Additional details

Currently (2023-05-24), it is possible to sign-in to GitHub EMU successfully on DevHome but no data shows up. Ideally, there would be a message about GitHub EMU not being supported after sign-in.

+1 Github Enterprise Server with Azure AD Creds

You should be able to sign into GitHub EMU today through the browser, but only 1 account at a time like with other clients.

GitHub Enterprise Server is on the roadmap. See #825.

Support for multiple accounts is also on the roadmap but requires dependent work from GitHub before we can enable. All other clients behave the same way today supporting 1 account at a time.

As Mike mentioned, Enterprise Server is tracked by 825, and multiple accounts is tracked by microsoft/devhomegithubextension#276. (There are updates in that one, so I'm going to leave it open, even though it's slightly newer than this one)
