Fix grunt-sass in the 5.0 branch

[azaozz]

Trying to build WordPress in a newly created checkout of the 5.0 branch fails as it tries to use very outdated node-sass dependency. Error message when doing npm install:

> node-sass@3.13.1 install [...]WordPress-5.0\node_modules\node-sass > node scripts/install.js Downloading binary from https://github.com/sass/node-sass/releases/download/v3.13.1/win32-x64-57_binding.node Cannot download "https://github.com/sass/node-sass/releases/download/v3.13.1/win32-x64-57_binding.node": HTTP error 404 Not Found

Removing npm-shrinkwrap.json (as in trunk) and updating grunt-sass to 2.0.0 in package.json fixes this problem (tested in fresh checkout on Win10).

Build/Test: Remove npm-shrinkwrap.json

Shrinkwraping is done to keep dependencies the same. Historically, WordPress Core has done it after a release. As the 5.0 branch was created from the 4.9.8 tag which was created from the 4.9 branch, it included it. The 5.0 branch will have some dependency updates so this shrinkwrap is not needed here.

See #45064.

Build/Test: Update dependencies for 5.0

Updates package dependencies to more modern versions, also adds .nvmrc and package-lock.json as followups to [43683] and [43571].

Merge notes: trunk already had an identical .nvmrc. package-lock.json exists in trunk, but has some changes based on the dependency updates.

Props jorbin.
Merges [43684], [43685] and [43686] to trunk.
See #44600.
Fixes #45064.
