feat: support Bun runtime

[lazarv]

This PR adds Bun support with a minimum version of Bun v1.1.45.

The most prominent change is the compatibility fallback workaround on how streams are being used with the SSR worker. Node.js supports passing streams to a worker, while Bun doesn't and it was necessary to pass buffers directly instead of using a stream.

Adds workaround to switch NODE_ENV to production when using @lazarv/react-server in production mode as React needs to resolve to the appropriate module in production.

A Bun plugin was implemented to resolve the react and react/jsx-dev-runtime modules to their react-server versions in development mode.

Using fsevents in file watchers is disabled when using Bun, while the server restart option is disabled in the development server when using Bun as there's a known issue with Vite restarting the server.

Fixes how the logger instance is initiated in production mode.

Updates the "Get Started" page in the documentation to include instructions on how to use Bun when working with @lazarv/react-server and also includes a minor tweak on the styling of the documentation sidebar navigation.
