Remove macOS tags

Is your feature request related to a problem? Please describe.
There doesn't seem to be a way to remove macOS tags on files/folders once they've been set.

Describe the solution you'd like
An action to remove macOS tags if they've been set, or an additional option on the macos_tags action such as mode: remove similar to how move and write have additional options.

Describe alternatives you've considered
I thought setting a tag of "none" would remove currently set tags, but that just seems to add a "none" tag in addition to the already set tags.

Additional context
If I tag a newly added file in a folder with e.g. blue to indicate it's newly added status, but want to remove the blue and set it to orange after a few days to indicate it's become stale, and finally to red after a week if it's become urgent, there's currently no way to do that since the macos_tags action just seems to append additional tags.
