Add serve host and hmr host options to the development script

[kadhirvelm]

Details

This PR exposes the host options for the development server (via --serve-host) and the hot module reload (via --hmr-host).

We would like these options exposed because our local development environment runs from inside a Docker container. We need a way to expose the development server and HMR that's running inside the Docker container to the local machine to make the development environment work properly.

For documentation, to get Plasmo's dev server to work from inside our docker container, we had to add the following ports configuration to our docker-compose file:

ports:
  - '0.0.0.0:1012:1012'
  - '0.0.0.0:1815:1815'
  - '0.0.0.0:1816:1816'

In addition to adding the flags in this PR. This would bind the sockets to 0.0.0.0 in both the docker container and the local machine, letting the extension bundle access everything correctly once loaded into the browser.
