Describe the Bug

This works:

// astro.config.mjs
export default defineConfig({
  server: {
    port: 3000,
    open: true,
  },

looking into the vite config though: https://vitejs.dev/config/server-options.html#server-open
this should also work:

export default defineConfig({
  server: {
    open: '/docs/index.html',
  },
})

but it doesnt:

[config] Astro found issue(s) with your configuration:
  ! server.open  Expected boolean, received string.

Follow up question: in the astro docs, open is not documented at all. Yet it still works. This is a little confusing.

What's the expected result?

Dev server should open at the designated path.
