Feature Request: Select between NGINX or Apache

### What

Hello! I think the idea of having a local WordPress site manager is great, but I have one comment: it shouldn't be possible to configure and change the type of server that the site will have in production, e.g. Apache or Nginx.

### Why

Some plugins make different use of this, especially image optimizers. I want to know if this is possible, thank you.

### How

_No response_

Start by locating how WordPress Studio provisions and configures the local web server, then compare the current assumptions with the Apache and NGINX requirements described here. The work is done when a site can explicitly select either server and the resulting local setup supports that choice; the issue does not name specific files or tests.
