fix(arborist): reject uninstall args that carry a version (#9881)

## What / Why

`npm uninstall vite@8.2.1` neither removes the package nor complains
about the argument. The spec goes straight through to Arborist as an
`rm` entry, nothing in the tree is named `vite@8.2.1`, so the reify
finishes with "up to date" and `npm ls` still shows `vite`.

`npm update` already validates its own argument list and throws
`EUPDATEARGS` for anything that is not a bare package name. This applies
the same rule to `rm`, so a version, tag or range now fails with
`ERMARGS` and the message names the command to run instead.

## Testing

New case in `workspaces/arborist/test/arborist/build-ideal-tree.js`,
next to the existing rm test and mirroring the update one. It covers an
exact version, a tag, ranges, a scoped name carrying a version, and a
filesystem path, where the suggestion falls back to `<pkg>` because
there is no name to print. It fails without the change.
