[dependabot-preview]

Bumps node-sass from 4.7.2 to 4.9.0.

Release notes

Sourced from node-sass's releases.

v4.9.0

Deprecations

[**import**](https://github.com/import)ing of .css files will produce a deprecation warning. This behaviour will be removed in node-sass@5.0.0.

This behaviour violates the Sass language specification. Additionally it makes it impossible to output to the input directory via the CLI or watcher.
