Node 14+ compatibility fix

[Freezystem]

This PR fix errors related to npm package extract-file imports that no longer works with recent version of node (at least v18.x.x and v19.x.x).
It seems that extract-file npm package.json prevent node from importing directly from files within public directory.

Here is the errors I got:

Error [ERR_PACKAGE_PATH_NOT_EXPORTED]: Package subpath './public/extractFiles' is not defined by "exports" in [...]/node_modules/extract-files/package.json

same goes for two other exports:

Error [ERR_PACKAGE_PATH_NOT_EXPORTED]: Package subpath './public/isExtractableFile' is not defined by "exports" in [...]/node_modules/extract-files/package.json

and

Error [ERR_PACKAGE_PATH_NOT_EXPORTED]: Package subpath './public/ReactNativeFile' is not defined by "exports" in [...]/node_modules/extract-files/package.jsonx

As extract-file index.js exports these directly I've just updated the imports.

Hi @Freezystem , thanks for you interest in contributing to the project :)

I had hoped to get to this PR today as it's a public holiday here in Victoria, Australia. Unfortunately I ran out of time after publishing https://github.com/jaydenseric/find-unused-exports/releases/tag/v5.0.0 .

Something to be aware of, is that there is a next branch I've been working on that's ahead of master:

https://github.com/jaydenseric/apollo-upload-client/commits/next

Work on it is paused until Apollo Client resolves this bug:
