[@nx/js] nx sync on windows machine fails due to path mismatch

[unknownbanana]

Current Behavior

When following the NX migration guide to PNPM workspace and TS project references and running nx sync to automatically update project references using the @nx/js:typescirpt syncGenerator we get a error message and sync fails to add project references.

Expected Behavior

We would expect there to be no path mismatch due to mixed useage of POSIX and Windows path seperators.

Additional Information

Seems to be caused by the use of a NodeJS join() when intializing the cache for tsconfig files when creating the project graph. [ https://github.com/nrwl/nx/blob/master/packages/js/src/plugins/typescript/plugin.ts#L1144 ]
