fix(providers): Add appid param to Azure AD wellKnown URL (#5138)

This fixes: #5137
Relevent documentation:
> If the application has custom signing keys as a result of using the claims-mapping feature, append an appid query parameter that contains the application ID to get a jwks_uri that points to the signing key information of the application, which should be used for validation.
