docs: add minimumDependencyAge to configuration reference

[aymenhmaidiwastaken]

Summary

• Added documentation for the minimumDependencyAge field in deno.json
• This supply chain security feature was added in denoland/deno#31007 but wasn't documented in the configuration reference
• Covers all supported value formats: number (minutes), ISO 8601 duration, and RFC 3339 date
• Documents the --minimum-dependency-age CLI override flag

Closes #3017

CI fails on deno fmt --check — the description paragraph (measure that helps protect against attacks where a malicious version is published / and quickly consumed before being detected.) is over the wrap limit. Run deno fmt and push.

Heads up: #3027 by @bartlomieju documents the same field with very similar examples. Worth coordinating on which lands — #3027 has external links to ISO 8601 / RFC 3339 specs and names --unstable-npm-lazy-caching as the activation flag, both worth folding in here.

• nit: the caution callout says "currently unstable" but doesn't tell the reader how to enable the feature. If --unstable-npm-lazy-caching is still required (per #3027), it should be on this page too.
• nit: last_modified: 2026-03-09 in the frontmatter wasn't bumped — repo convention is to bump it for substantive content changes.

Thanks so much for putting this together, @aymenhmaidiwastaken! The minimumDependencyAge documentation is now covered as part of the Deno 2.8 docs update in #3100, which adds a dedicated section under the supply-chain security guide (including all value formats, the --minimum-dependency-age CLI flag, and the .npmrc equivalent). Closing this in favor of #3100 — really appreciate you taking the time to document this!
