tctl request rm for an already approved request responds with a help message and command that has an error in it

[WilliamLoy]

Expected behavior:
That tctl request rm responds with the correct syntax for locking and already approved request.

Current behavior:
tctl request rm for an already approved request responds with a help message and command that has an error in it

tctl lock --access_request should be tctl lock --access-request

Bug details:

• Teleport version : 10.0.2 and 9.3.10
• Recreation steps
• 1. create and approve and access request. 2. attempt to remove the access request via CLI. 3. produce error using the --access_request flag that the help message recommends.
• Debug logs
