Unable to use Color Replacements option in the `Rehype` plugin

[fwqaaq]

Hey, bro:

I've encountered an issue while using rehypeShiki. Although the plugin's TypeScript definitions include a CodeToHastOptions type with a Replacements option, I'm unable to utilize the Replacements option in practice.

See: https://shiki.style/guide/theme-colors#color-replacements

// Don't replace bg `#23262E` to `#48458A`
    .use(rehypeShiki, {
      theme: "andromeeda",
      defaultColor: false,
      addLanguageClass: true,
      colorReplacements: {
        "andromeeda": {
          "#23262E": "#48458A"
        }
      }
    })
