Drop-in hyperx-void as a replacement for hyperx

## Summary
In order to support self-closing tags, we want to pull in `hyperx-void` and have any project that would pull in `hyperx` to use `hyperx-void` instead.

Not exactly sure what's involved to get our dependencies to use `hyperx-void` instead of `hyperx`, I would prefer to not modify any package-lock or shrinkwrap files, if that's possible.
