Add Keyless SSL "Run with Docker" page + container debug logging note

[baubuchon-cf]

What this changes

Adds container/Docker documentation for the Keyless SSL key server (gokeyless), addressing gaps reported by an enterprise customer (T257).

• New page — Run with Docker (configuration/run-with-docker.mdx): pulling the ghcr.io/cloudflare/gokeyless image, a full KEYLESS_* environment-variable reference, how to configure private keys (config block / --private-key-dirs — not an env var), a runnable docker run example, and serving multiple private keys.
• Troubleshooting — Enable debug logging: adds a container variant. The existing sudo -u keyless gokeyless --loglevel 0 command assumes a host/systemd install and does not apply in a container (gokeyless is PID 1); documents setting KEYLESS_LOGLEVEL at startup and reading logs via docker logs / kubectl logs.

All environment-variable names, defaults, ports (2407/2406), precedence (flag > env > config), and the private-key mechanism were verified against gokeyless master source (cmd/gokeyless/gokeyless.go).

3 style guide items to address before merge.

[ask-bonk]

Posted a review with 3 inline suggestions on PR #31852 and applied labels: documentation, product:ssl, content:new, triage.

Verdict: No blockers — the content is technically accurate and the new page fills a real gap. Three minor style-guide items need fixing.

Issues to address:

• LOW — run-with-docker.mdx:70: Heading uses a gerund ("Serving multiple private keys"). Style guide requires imperative mood for section headings: "Serve multiple private keys".
• LOW — run-with-docker.mdx:47-50: Bullet list has only 2 items. Style guide says do not use bullets for fewer than three items; rewrite as a sentence.
• LOW — troubleshooting.mdx:39: Placeholders <container> and <pod> should follow the ALL_CAPS_UNDERSCORES convention: <CONTAINER> and <POD>.

Out-of-scope note: The troubleshooting page contains a pre-existing bash output code block (lines 68–87) that ideally should use txt output, but that is outside this PR's diff.

@elithrar -when you have a moment, could you review for CODEOWNER approval? New "Run with Docker" page + a container debug-logging note in Troubleshooting. All bot checks green; every claim verified against gokeyless master (code-verified, not runtime-tested). Small and self-contained. Thanks!
