feat(adfs): Display Number Match

[DanielMuller]

Microsoft introduced Number Match with ADFS MFA. This PR grabs the validEntropyNumber from the HTML and display's it to the user.

This is great. Would be great to get this merged into main! Thanks.

I have the same issue.... tested this PR and works perfectly!

Since my initial PR, it seems that Microsoft has changed the way they request for number matching. The number is now prompted in the UI and needs to be entered in the Authenticator App. This change was already merged (#857), making my PR obsolete.
