[bug] v1.33.0 rejects valid ::search-text:current and ::search-text:not(:current) selectors

[rvitaliy]

Description

Lightning CSS 1.33.0 rejects these valid selectors:

::search-text:current
::search-text:not(:current)

Both are required by the Web Platform Tests for ::search-text and were
accepted by Lightning CSS 1.32.0. The regression affects both lightningcss
and lightningcss-wasm.

Reproduction

npm install lightningcss@1.33.0

import { transform } from "lightningcss";

for (const selector of [
  "::search-text:current",
  "::search-text:not(:current)",
]) {
  transform({
    filename: "input.css",
    code: Buffer.from(`${selector} { color: red }`),
    minify: true,
  });
}

Both calls fail with:

Invalid pseudo class after pseudo element, only user action pseudo classes (e.g. :hover, :active) are allowed

Expected result

Both selectors should be accepted and minified.

Support for ::search-text was added in #1213, but its tests do not cover
these two forms.
