Feature description

We've been using Keycloak for a while now. However, we are still using the old version pinned to 15.0.2 , with the recent need for ARM builds and focusing on better support and reliability of Nebari, I suggest we start looking into the feasibility of this.

This might not be a straightforward move, as we can't yet guarantee that all those versions released so far are backward compatible or if the database would be the same. (Though, we could overcome this easily by developing further #1784 )

Value and/or benefit

• Support for the latest changes and security fixes on keycloak
• Support for ARM image builds without requiring extra maintenance burden on our side
• More control on permissions and groups with the recent updates made to the UI

Anything else?
