[scss] support passing arguments to content blocks in mixins

Issue Type: Bug

As of Dart Sass 1.15.0, sass supports passing arguments to content blocks in mixins.

For example,

@mixin rtl($ltr-dir) {
    .dir_ltr & {
        @content($ltr-dir);
    }
}

@include rtl("left") using ($dir) {
    margin-#{$dir}: 10px;
}

Is valid, but vscode scss lint reports errors, notably "scss(css-semicolonexpected)" after the @content and the using keyword
