📚 Revise instructions on prerequisites

* Do not state that pnpm must be available after Node.js installation
  (it is installed by corepack)
* Do not state that caddy is required; it is required only when
  rebuilding the API documentation for the server, which is not
  a task relevant to regular users.
* Do not strongly suggest that MCP users should be using the devenv.
* Windows: Add pointer to use Git Bash
