Update dependency stylelint to v16.18.0

| datasource | package   | from    | to      |
| ---------- | --------- | ------- | ------- |
| npm        | stylelint | 16.17.0 | 16.18.0 |


## [v16.18.0](https://github.com/stylelint/stylelint/blob/HEAD/CHANGELOG.md#16180---2025-04-06)

It adds 2 new rules and fixes 2 bugs. We've turned on these rules, and the `syntax-string-no-invalid` and `layer-name-pattern` ones from recent releases, in our [standard config](https://www.npmjs.com/package/stylelint-config-standard).

-   Added: `color-function-alias-notation` rule ([#8499](stylelint/stylelint#8499)) ([@EduardAkhmetshin](https://github.com/EduardAkhmetshin)).
-   Added: `container-name-pattern` rule ([#8498](stylelint/stylelint#8498)) ([@nate10j](https://github.com/nate10j)).
-   Fixed: `declaration-property-value-no-unknown` false positives for `math` of `font-size` ([#8495](stylelint/stylelint#8495)) ([@otomad](https://github.com/otomad)).
-   Fixed: `font-family-no-missing-generic-family-keyword` false positives for `math` ([#8489](stylelint/stylelint#8489)) ([@otomad](https://github.com/otomad)).
