refactor(init): remove unmaintained resolve-package

[erickzhao]

This PR removes the unmaintained resolve-package module in favour of using resolve.require directly for global modules.

Uses global-dirs to fetch the cross-platform values of npm root --global and yarn global dir without shelling out to a child process.

Note: we can't use await import for ESM-only moules in Forge at the moment because of our tsconfig.json values, so we're using global-dirs in this PR instead of the newer global-directory package.
