Fix Astro.url.protocol when using the @astrojs/node SSR adapter with HTTPS

[HiDeoo]

Changes

This PR fixes #5890.

When using Astro with the @astrojs/node SSR adapter, Astro.url.protocol is always http: even when the server is running with HTTPS.

When creating the request used during rendering based on the Node.js request, the protocol is currently hardcoded to http:.

This pull request fixes this issue by checking if the Node.js request is using HTTPS and updating the protocol accordingly. To do so, we check if the request socket is either an instance of tls.TLSSocket or if the X-Forwarded-Proto header is set to https.

While testing this, I also realised that when starting the server, the console is always logging a URL with the HTTP protocol, e.g. Server listening on http://127.0.0.1:3000. I decided to include a small change in this PR to log the proper protocol by checking if the server is an instance of https.Server or not. I thought this was not worth a different PR or even mentioning it in the changeset but maybe I was wrong?

Testing

I added new @astrojs/node tests in a url-protocol suite using a fixture rendering a page with Astro.url.protocol and checking the rendered HTML based on the protocol of the Node.js request.

I also manually tested locally this change in a local repro using the file: pnpm protocol and confirmed that logging Astro.url.protocol correctly return https: when running with SERVER_KEY_PATH=./key.pem SERVER_CERT_PATH=./cert.pem node ./dist/server/entry.mjs

Docs

I don't think this change needs to be documented.
