Unable to import fontkit's package.json in dependent packages

[fstrube]

Packages that depend on fontkit are no longer able to obtain version information and other metadata by importing fontkit's package.json. Previously, we were able to do something like this:

const fontkitVersion = require('fontkit/package.json').version;

// or

import fontkitPackage from 'fontkit/package.json' assert {type: 'json'};

const fontkitVersion = fontkitPackage.version;

Now, we receive an ERR_PACKAGE_PATH_NOT_EXPORTED error when attempting to import the package.json file.

Error [ERR_PACKAGE_PATH_NOT_EXPORTED]: Package subpath './package.json' is not defined by "exports"
