sql: check privileges in CONFIGURE ZONE commands

[jseldess]

PR: cockroachdb/cockroach#40879

From release notes:

CONFIGURE ZONE statements now fail if the user does not have sufficient privileges. If the target is a system range, the system database, or a table in the system database, the user must have an admin role. For all other databases and tables, the user must have the CREATE privilege on the target database or table. This change might be backward-incompatible for users running scripted CONFIGURE ZONE statements with restricted permissions. To add the necessary permissions, use GRANT <privileges> or GRANT <roles> as a user with an admin role. For example, to grant a user the admin role, run GRANT admin TO <user>. To grant the CREATE privilege on a database or table, run GRANT CREATE ON [DATABASE | TABLE] <name> TO <user>. [#40879][#40879] {% comment %}doc{% endcomment %}

This was fixed by #5609.

When I merged that PR, I referenced the wrong issue that it fixed.
