Prepare documentation for DocumentDB 0.117

[GuanzhouSong]

Summary

• Update current package assets, versioned container examples, and release links to published v0.117-0.
• Document StoreData sample loading and the 117 RUM default; correct PG17 meta-package selection and retired repository guidance.
• Preserve historical version notes and the explicitly labeled v0.114 PostgreSQL API reference.

Validation

• All 12 example package filenames match the published 117 assets.
• Markdown metadata/code fences and release/setup/sample invariants checked in Docker; git diff --check passed.
• Container argument behavior and RUM defaults checked against the released tag.

Merge this docs update before the companion website update: website builds fetch documentdb/docs@main.
