Set up a properly capitalized label for Microsoft OAuth2

Problem to solve

As noted in this Azure OAuth MR, our label for Microsoft Azure Oauth2 is improperly capitalized (it should be Azure OAuth2)

Intended users

Anyone whose configuring OAuth2 auth between Azure AD and GitLab. Selected personas are my "best guess".

Further details

Proposal

The solution, I think, is to add a label to the provider.rb file, which already includes labels to address similar problems.

So in this code block, I'd add an azure_oauth2 line, as shown:

      class Provider
        LABELS = {
          "github"         => "GitHub",
          "gitlab"         => "GitLab.com",
          "google_oauth2"  => "Google",
          "azure_oauth2"   => "Azure OAuth2"

Permissions and Security

Documentation

Documentation is n/a; however, this change would make our label consistent with the way we capitalize OAuth2 in our docs.

Testing

What does success look like, and how can we measure that?

What is the type of buyer?
