Errors on `@supports` syntax

[wolfy1339]

Bug report

Actual Behavior

I'm trying to compile a Sass file that uses the @supports syntax

The culprit is from the @prime/view-components package which is required by @primer/css

@supports not selector(:popover-open) {
    [popover]:not(.\:popover-open) {
        display: none
    }
}

Error message:

ERROR in ./src/style.scss
Module build failed (from ./node_modules/sass-loader/dist/cjs.js):
Invalid CSS after "@supports not": expected "{", was "selector(:popover-o"

 @ ./src/main.js 3:0-22

webpack 5.93.0 compiled with 1 error and 1 warning in 9903 ms

Expected Behavior

The plugin should accept the @supports syntax

How Do We Reproduce?

I'm seeing this issue in https://github.com/probot/smee.io/tree/update-deps

The problematic file is https://github.com/primer/view_components/blob/main/app/components/primer/alpha/dialog.pcss#L24
