rm: expose main functionality for nushell #5294
Description
Part of: nushell/nushell#10447
nushell wants access to our rm internals. Which means exposing the remove function and Options struct. There should be documentation for all the public items in the API as well.
This is an excellent first issue: feel free to claim this!
We did the same thing for cp already. You could use that PR as a guide: #5152
