Remove Alpine 3.22 images

[Copilot]

Per the supported platforms policy, Alpine 3.22 images stop publishing 3 months after Alpine 3.23 release (March Patch Tuesday).

• Dockerfiles: Removed 28 Alpine 3.22 directories (84 Dockerfiles) across runtime-deps, runtime, aspnet, and sdk for .NET 8.0/9.0/10.0
• manifest.json: Removed all Alpine 3.22 image entries and shared tags
• manifest.versions.json: Removed libssl|alpine3.22
• MCR tags metadata: Removed 28 Alpine 3.22 tag group references
• Documentation: Updated alpine3.22 → alpine3.23 in sample-image-size-report.md and vulnerability-reporting.md
• Tests: Removed OS.Alpine322 and associated test data entries
• Regenerated Dockerfiles, READMEs, and internal Dockerfile baselines from templates

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)
