Highlighted region in Authentication

[bennycode]

Changes

Please describe both what is changing and why this is important.

The value {YOUR_TENANT_AND_REGION}.auth0.com was a bit misleading for me. It took me some time to realize that I needed to enter auth-sp-staging.eu.auth0.com in my case. The region is separated from the tenant by a ., which I think is important to highlight.
