`hsla` parsing no longer working

Passing Daisy CSS vars to `hls()` works as expected but `hsla()` ignores the values.

For a quick test of the issue, add the following snippet to any text element in the [`demo/index.html`](https://github.com/kidonng/unocss-preset-daisy/blob/main/demo/index.html):

```css
style="color: hsla(var(--wa), 0.5)"
```
