cli: don't advertise --tenant-name-scope just yet

Implementation to authenticate using tenant name scopes from the client certs is not ready yet. Defer advertising the cli flag till it is ready.

Fixes: cockroachdb#133168
Epic: CRDB-43487
Release note (multi-tenancy): Hide --tenant-name-scope cli flag until the implementation is ready.
