Dependency deprecation warning: gulp-util (nvm)

On registry `https://registry.npmjs.org`, the "latest" version (v3.0.8) of dependency `gulp-util` has the following deprecation notice:

`gulp-util is deprecated - replace it, following the guidelines at https://medium.com/gulpjs/gulp-util-ca3b1f9f9ac5`

Marking the latest version of an npm package as deprecated results in the entire package being considered deprecated, so contact the package author you think this is a mistake.

Please take the actions necessary to rename or substitute this deprecated package and commit to your base branch. If you wish to ignore this deprecation warning and continue using `gulp-util` as-is, please add it to your [ignoreDeps](https://renovatebot.com/docs/configuration-options/#ignoredeps) array in Renovate config before closing this issue, otherwise another issue will be recreated the next time Renovate runs.

Affected package file(s): `package.json`

Start with package.json and inspect the gulp-util dependency and its usage. Follow the replacement guidelines in the linked deprecation notice, then verify that the dependency is replaced; if it should remain, add it to Renovate's ignoreDeps configuration instead.
