Incorrect documentation: bench update --bench

[SvbZ3r0]

The Frappe Framework docs mention a bench update --bench command. However, it results in Error: No such option: --bench. The --help command doesn't mention the --bench flag either.

The archived Frappe Docs repo points to https://frappeframework.com/contribute for contribution guidelines for the documentation. But following the link results in a HTTP 417 with the following error traceback.
