[Feature Request] Standardize Command Option string-enum value format

[yuandrew]

Is your feature request related to a problem? Please describe.

Some use camel case (type has values like FirstWorkflowTask), others use snake case (reject-condition has not_open), some capitalize the first letter (reapply-type has All), others are all lowercase (wait-for-stage has accepted). This is likely a product of history.

Describe the solution you'd like

We should land on a standardized format for this. But we also need to make sure we support aliasing the old options for backwards compat

Additional context

[yuandrew]

log-format needs to be changed to string-enum, but pretty needs to be a undocumented legacy alias

This would be a nice to have, but there are global temporal values here that would be changed, and it's a larger scope to address, and not something that's necessarily worth it at the moment. Maybe worth revisiting once tctl has been archived, that might make this easier.
