Absolute path to the @mdx-js/tag

[jeetiss]

The @mdx-js/tag dependency is not resolving if loader used with such builders as razzle, next etc.
I've added the absolutePath option to loader to make it able to resolve @mdx-js/tag in this case.

It works fine with Next.js though. Maybe razzle doesn't add the extra node_modules directory to the resolve key in webpack.
