[Feature Request] Add a `patch` semantics option to CLI and/or support a `temporal schedule describe -o cli` command

[GSmithApps]

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

The CLI for schedules only supports put semantics, and not patch semantics, which would be convenient for simple changes.

Describe the solution you'd like

I’d like an option to do patch semantics and/or support a temporal schedule describe -o cli command.

Additional context

Right now, when users want to update schedules, they often resort to a python script instead of the CLI
