[DXM-100] Add Redis TLS config shared component

[bignimbus]

Summary

Resolves DXM-100.

The docs mention that any Redis connection supports a TLS config, but this information only lived in a single spot (TLS configuration overview) that users were unlikely to discover when reading a feature page directly (APQ, Entity Cache, response caching, etc.).

This PR:

• Updates the existing shared component docs/shared/redis-tls.mdx with generic, feature-agnostic content and a clean YAML example showing just the redis.tls block structure
• Imports and renders that shared component on every feature page that exposes a Redis configuration section:
  • docs/source/routing/operations/apq.mdx (APQ distributed caching)
  • docs/source/routing/query-planning/caching.mdx (query plan distributed caching)
  • docs/source/routing/performance/caching/response-caching/customization.mdx (response cache advanced Redis config)
  • docs/source/routing/security/tls.mdx (TLS overview — Redis section)
• Removes duplicate inline TLS content from each of those pages (55 lines of duplication eliminated)

Acceptance criteria

• Redis TLS config info is now visible contextually on each feature page that configures Redis
• A single shared component (docs/shared/redis-tls.mdx) is the single source of truth for the Redis TLS blurb
• The shared component links back to the full TLS configuration page for comprehensive details

Jeff's direction

You'll need to work from the repo apollographql/router. From the project root, look for docs/source/routing/configuration/overview.mdx. Search for other Redis TLS config references per the ticket, you'll need to look over everything in the /docs/ directory (including nested directories) to find all the areas where we could include this shared context.

⚠️ AI Style Review — 6 Issues Found

Summary

The documentation has been updated to align with the style guide across several sections. In structural-elements, changes include specifying programming languages for syntax highlighting, closing code blocks, and ensuring two newlines are used within admonition components for correct formatting. Text-formatting was improved by replacing vague links with descriptive noun phrases. In framing and voice, instructions were updated to use the imperative mood and an authoritative, helpful tone was adopted by removing permissive phrasing like 'you can' to ensure actionable content.
