ref(notifications): remove UserNotificationSettingsDetailsEndpoint (#…

…60302)

The endpoint `UserNotificationSettingsDetailsEndpoint` is no longer
being used by either the UI or the API as shown by this
[query](https://redash.getsentry.net/dashboards/197-endpoint-usage).
They are also not documented so we can just remove them.

Note I had a previous PR that removed `UserNotificationDetailsEndpoint`
which was a mistake. We can remove some functionality from it but can't
be removed just yet.
