`view-transition-name: match-element` is incorrectly transformed

[tomtuv]

When using CSS Modules, LightningCSS transforms the standard CSS keyword match-element when used with view-transition-name.

Input:

.example {
  view-transition-name: match-element;
}

Current output:

.example {
  view-transition-name: SkZWNq_match-element;
}

Expected output:

.example {
  view-transition-name: match-element;
}

It looks like the CSS Modules scoping/transformation logic currently treats match-element as a custom identifier, even though it is a reserved keyword defined by the spec: https://drafts.csswg.org/css-view-transitions/#view-transition-name-prop
