templ CLI --proxy option and hot reload

[eussam]

Hi,
I think it would be interesting for clarification to add a concrete example to the documentation about how to use the --proxy option with the --cmd option to setup hot reload with templ CLI.
@a-h do you think it could be interesting and if so shall I open a PR ?

Sorry, I missed this discussion. I would have loved a PR too on it too! 😁
