coder update cli command doesn't explain it needs an arg #3299
Description
Problem
% coder update -h
Update a workspace to the latest template version
Usage:
coder update [flags]
This usage is incorrect, as it needs a workspace name as an arg.
Also, we panic instead of giving an error message when you run it without a workspace name
% coder update
panic: runtime error: index out of range [0] with length 0
goroutine 1 [running]:

Acceptance criteria
- usage should be
coder update <workspace> [flags] - running
coder updatewith no args should throw an error (or prompt user for workspace)
