[docs] Add OKLCH palettes
We should document colors-oklch.min.css and gray-oklch.min.css for folks who want to use dynamic palettes.
Also include these links as usage guides:

They’re fantastic, especially the lightness and the chroma, which make maintaining accessibility so straightforward. Really well done, great job Adam!

We’ll see in the future how they scale. For now, I think the author has enough flexibility with relative colors, and they can always fall back to static hex if needed.
We could add a second palette later to support the main colors-oklch, but for now these should be more than enough.
We should also consider renaming the gray props in gray-oklch.min.css to --hdr-gray so they don’t conflict with the hex version, as mentioned in issue #388. Before adding them to the docs, this feels like the right moment to make that change.
