chore(plugin-multi-tenant): use beforeNav instead of beforeNavLinks for tenant selector (#15499)

Updates the tenant selector to use the new beforeNav component slot
instead of beforeNavLinks, placing it before the entire navigation
section for better UI placement in the future if a user enables sidebar
tabs.
