node-gyp 6.0.0 upgrade (resolves python2 dependency)

[neilsh]

Currently ttf2woff2 requires node-gyp 4.0, which requires python2 (instead of python3). This has led to issues like https://github.com/nfroidure/ttf2woff2/issues/37 and https://github.com/nfroidure/ttf2woff2/issues/28

Earlier this month node-gyp released version 6.0.0, which accepts python3 (https://github.com/nodejs/node-gyp/pull/1844). This PR upgrades the package.json and package-lock.json to node-gyp 6.0.0.

I've verified it builds with the new node-gyp version:

$ node-gyp --version
v6.0.0

Thanks, I'll just try it on my setup before merging, doing this asap.

hi @nfroidure , gentle reminder to check if you've had a chance to test it yet :)

Could we get a release that includes this? Your other package, gulp-iconfont, needs it.
