Issue

Vite has the option to generate assets for ssr builds.

https://main.vitejs.dev/config/build-options#build-ssremitassets

Currently @fastify/vite only serves client assets, could it be updated to also serve ssr build assets?

Something like:

  await this.scope.register(async function staticContext (scope) {
    await scope.register(FastifyStatic, {
      root: [resolve(clientDist, assetsDir), resolve(serverDist, assetsDir)],
      prefix: `/${assetsDir}`
    })
  })

Yep, that sounds like a reasonable thing to do. Can you open a PR with that change? I'll review and test then.
