feat: wait next server is available

[Debbl]

Using get-port-please to wait the renderer process port is available, And set default starterUpDelay is 10_000 ms.

    await waitForPort(rendererPort, { delay: 500, retries: startupDelay / 500 })
      .catch(() => {
        logger.error(`Failed to start renderer process with port ${rendererPort} in ${startupDelay}ms`)
        killWholeProcess()
        process.exit(1)
      })
