docs(minimum-release-age): filter disabled dependencies from timestamp query

[Boulea7]

Changes

The documented jq query now excludes dependencies with enabled: false from missingCurrentVersionTimestamps. Dependencies where enabled is unset, true, or null remain in the result, and the missingReleaseTimestamps query is unchanged.

I ran the query against the redacted log from discussion #40720: a disabled dependency appears with the current query and is excluded with this change. A smaller sample also covered all four enabled states. The targeted check, Markdown lint, fenced-code check, docs tests, and docs build pass.

Context

• This closes an existing Issue, Closes: docs(minimum-release-age): filter out enabled: false dependencies in missingCurrentVersionTimestamps script #40725
• This doesn't close an Issue, but I accept the risk that this PR may be closed if maintainers disagree with its opening or implementation
