fix: remove `node-pre-gyp` dependency

[styfle]

In a previous PR (#206), support for @mapbox/node-pre-gyp was added and the legacy node-pre-gyp was kept around for backwards compatibility.

However, these packages are currently identical besides changing ES5 to ES6 (var => const) should be backwards compatible and safe to drop node-pre-gyp.

• Screenshot of lib/util/versioning.js diff

This will remove the deprecation warning:

Please upgrade to @mapbox/node-pre-gyp: the non-scoped node-pre-gyp package is deprecated and only the @mapbox scoped package will recieve updates in the future
