Update OIDC Spotify properties

[sberyozkin]

This PR makes it a bit easier to use Spotify provider:

• User name can now be extracted from the injected UserInfo as userInfo.getDisplayName()
• For the above to work, another scope user_read_private is added (it is like profile scope we add to Github/Google/etc provider definitions - it won't go unnoticed by the users, Spotify authorization screen will let them know), and also a principal claim name is customized as display_name (Spotify specific claim name)

Also, an access token is binary so to verify it one would need to fetch UserInfo (so a property is added to the provider definition, same as we do for other social providers producing binary tokens) and a minor update is done to the deployment code for Provider: Spotify link to appear in Dev UI OIDC card
