Tldr: trash: add trash-rm commands

[jxu]

Use case: permanently deleting file (removing from trash)

Right now tldr trash lists commands for trash and related functions: trash-list, trash-restore, trash-empty, but not trash-rm

From trash-rm man page:

EXAMPLE
       $ trash-rm foo          # Removes all files with name 'foo' in trash can
       $ trash-rm '*.o'        # Removes all files ending with '.o' in trash can
       $ trash-rm /full/path   # Removes all files removed with exactly '/full/path' as original location

Thanks for requesting this change! Do you want to have a go yourself?

Pages are best maintained by people who understand the command they are about.

If you do, take a quick read of CONTRIBUTING.md, which guides you through the process of creating or changing a page here. Then, just simply send a pull request to this repository - and if you need any assistance, just ask :-)

Ok I went ahead and made a PR.
