Refs #37151 - Fix --force flag to use option_override_name

[jeremylenz]

#977 should have validated option_override_name, but inadvertently looked at option_value instead. This caused hammer content-override to break completely.

Turns out our Hammer tests were also wrong. Params should be like

--override-name enabled
--value true

--override-name enabled
--value 1

but instead were like

--value enabled

To test:

hammer activation-key content-override --id 2 --content-label satellite-client-6-for-rhel-9-x86_64-rpms --value true
hammer activation-key content-override --id 2 --content-label satellite-client-6-for-rhel-9-x86_64-rpms --override-name foo --value 0

1. Without the --override-name flag, values true, false, 0, and 1 (and really, any value) should work.
2. With the --override-name of enabled, the values above should also work.
3. With the --override-name of anything other than enabled, you should get the (new & improved) error

Could not update content override:
  You must use --force to set an override other than 'enabled'

Code looks great, ACK
