[docs-agent] Deprecate Aptos and Avalanche Snapshots tutorial pages

[JackReacher0807]

Summary

The Aptos and Avalanche Snapshots features have been deprecated. This PR rewrites both tutorial pages as short deprecation notices and drops the now-dead links to alchemy.com/snapshots/aptos and alchemy.com/snapshots/avalanche.

Slugs (docs/snapshots/aptos, docs/snapshots/avalanche) are unchanged, so any inbound links from blog posts, indexers, or external sites land on the deprecation notice rather than 404. Nav (content/docs.yml) and redirects.yml therefore need no changes. The other 5 chains in content/tutorials/snapshots/ (Ink, Shape, Soneium, Unichain, Worldchain) still have an active snapshot service and are untouched.
