fix: make plugin compatible with Docusaurus beta.13

[Josh-Cena]

Fix #87. See facebook/docusaurus#6047. This change was made in the core to resolve circular dependencies. Sorry for not marking it as breaking change—we aren't expecting anyone to use such implementation detail (at least previously). As now it's found its home in utils, we can assert that it will be stable as long as the architecture isn't completely overhauled.

Haha no worries, I assumed importing directly from the lib folder would be fragile and have unannounced breaking changes. I appreciate the PR ❤️

This is hard 🤦‍♂️ Because of facebook/docusaurus#6087 the theme fails to build, but the theme-classic/index file is only used to import a type that we don't use... I tried skipLibCheck with no luck. If this project is using Yarn berry I would suggest doing a patch package. @bourdakos1 would you be willing to migrate to Yarn berry?

@Josh-Cena Oh, wow thanks for all the work you've put in to this! I think I can fix the typescript issue. I'll checkout your branch and see if I can get it working

Oh hehe, I did add declare module for the theme but I forgot to add it to the preset... Thanks for the fix

[bourdakos1]

No problem :) Thanks for everything you've done, really appreciate it
