Twitter authentication is no longer working. Microsoft needs docs update

[EternallLight]

Description

I've set up everything as closely as per insturctions, and when trying to authenticate with Twitter, I'm getting this at https://comments.mydomain.com/auth/twitter/login?from=https%3A%2F%2Fcomments.mydomain.com%2Fweb%2Fiframe.html%3FselfClose&site=reactlibs

{
  error: "failed to get request token"
}

After some local debugging, it appeared the Twitter retuns an error during the initial attempt of getting a token from it. I suppose it's been a while since someone checked on it.

Remark 42 is still using the Twitter icon instead of the new X icon. Probably something has changed besides the name, and surprising Twitter asked me for money for using their API whereas attempting to hide the "free" button.

Overall, I'm just letting you know that it's no longer working as expected.

Microsoft Issue

Besides Twitter, Microsoft authentication also didn't work from the start, failing with the request is not valid error.

This Stackoverflow answer helped me to get it rolling:

You can simply go to the portal Azure panel, open the Manifest section, and change the signInAudience's value from PersonalMicrosoftAccount to AzureADandPersonalMicrosoftAccount. If it doesn't exist, create both key and value.

I'd recommend to add this to the docs.

From what I recall, Twitter (X) doesn't allow auth method remark42 is using for a couple of years. @paskal do you recall details?

@EternallLight could you please update Microsoft auth instructions here and in go-pkgz/auth?

As for Twitter, last discussion on the topic was here and I don't think anyone figured out how to make it work. I think we should leave its support in case it works for someone, but deprecate the parameters and remove the mentions from documentation.
