fix: unpublish bugfixes (#7039)

- Properly work in workspace mode.  Previously setting the workspace
  meant the entire package was unpublished.  Now it follows the
  convention of acting as if you were running from the workspace
  directory.
 - Better checking of when you are unpublishing the last version of a
  package.  npm checks the actual manifest and compares it to the
  version you are asking to unpublish.
 - Error on ranges and tags.  npm doesn't unpublish ranges or tags, and
   giving those as inputs would give unexepected results.
 - Proper output of what was unpublished.  Previously the package (and
   sometimes version) displayed would not match what was actually
   unpublished.
 - Updated docs specifying that unpublishing with no parameters will
   only unpublish the version represented by the local package.json
