Rules are not ignored when using SCSS namespace

[kimulaco]

Overview

If you use the new Sass @use rule namespace, the rule will not be ignored and an error will occur.
I know the point to correct, so I will issue a PR!

I got a "font-family-no-missing-generic-family-keyword" error under the following circumstances.

// src/scss/_font.scss
$font-family-default: Arial, sans-serif;

// src/scss/_button.scss
@use "font" as font;

.button {
  font-family: font.$font-family-default;
}

src/scss/_button.scss
 4:16  ✖  Unexpected missing generic font family   font-family-no-missing-generic-family-keyword
