fix(cli): improve error message when language in list can't be found (#4643)

Browse source 
Problem: When multiple input paths are provided to the `parse` command (a la `tree-sitter parse --paths [...]`), if a language can't be found for one of the paths, it can be a little unclear *which* path caused the failure. The loader *can* fail with `Failed to load language for file name <foo.bar>`, but this isn't guaranteed.

Solution: Attach some additional context in the case where multiple paths can be provided, displaying the problematic path on failure.
