📚 Is your documentation request related to a problem?

the build.config.ts form https://regexp.dev/guide has some typeerrors.

import { MagicRegExpTransformPlugin } from 'magic-regexp/transform'
import { defineBuildConfig } from 'unbuild'

export default defineBuildConfig({
  entries: ['./index.ts'],
  declaration: true,
  hooks: {
    'rollup:options': (options, config) => {
      config.plugins.push(MagicRegExpTransformPlugin.rollup())
    },
  },
})

ERROR:

        ~~~~~~~~~~~~~~
