closing/removing button for previewing a workflow interface

[JLSteenwyk]

Is your feature request related to a problem? Please describe.
The preview function is great for designing the workflow interface, however, I'd like to remove the button now that I no longer need the preview function.

Describe the solution you'd like
Ideally, I would like to add an argument to latch preview <workflow_function_name> command to be something like latch preview <workflow_function_name> --remove or latch preview <workflow_function_name> -r. Then, it would be great if this could be added to the docs: https://docs.latch.bio/basics/preview_interface.html
