We missed the fallback to the v1 ShowDatabasesCommand.

@cloud-fan could you clarify on the fallback?
"show databases" and "show namespaces" were merged by #26006 and both are handled by v2 ShowNamespacesExec.

Ah I misremember that. So we forgot to add a migration guide for the schema change... (databaseName -> namespace) Anyway it's too late now, let's catch schema changes in the following development work.

This is a follow-up to address the following comment: #27095 (comment)
Currently, a SQL command string is parsed to a "statement" logical plan, converted to a logical plan with catalog/namespace, then finally converted to a physical plan. With the new resolution framework, there is no need to create a "statement" logical plan; a logical plan can contain
UnresolvedNamespacewhich will be resolved to aResolvedNamespace. This should simply the code base and make it a bit easier to add a new command.Why are the changes needed?
Clean up codebase.
Does this PR introduce any user-facing change?
No
