Merge #147666

147666: sql: add function and procedure to \h show create r=Dedej-Bergin a=Dedej-Bergin

Previously `\h show create;` did not show FUNCTION or PROCEDURE in the CLI doc. With these changes we can now see them.

Fixes: #146679
Epic: CRDB-49398

Release note (bug fix): `FUNCTION` and `PROCEDURE` are now shown via `\h show create` in the CLI doc.
