[Ramps] Hide subscription management buttons in Gitlab group billing page for ramp subscriptions
For ramp subscriptions, we need to hide the subscription management buttons i.e. Add seats
and Renew
buttons in the Gitlab.com group billing page since customers can't add seats or renew a ramps subscriptions themselves but they need to contact sales.
The Manage
button should be visible (no change).
