fix: point homebridge custom versioning at ghcr.io

[Principe1218]

Description

⚒️ Fixes # N/A — companion to trueforge-org/truecharts#50995

trueforge-org/truecharts#50995 switches the homebridge chart's image.repository from docker.io/homebridge/homebridge to ghcr.io/homebridge/homebridge. The custom versioning rule for homebridge's date-based tags (YYYY-MM-DD treated as major.minor.patch) currently matches on matchPackagePatterns: ["docker.io/homebridge/homebridge"]. Once that PR merges, the pattern would stop matching the new package name, and Renovate would fall back to default SemVer versioning — which can't parse date tags — so future homebridge releases would silently stop being picked up again. This updates the pattern to match the new registry.

⚙️ Type of change

• ⚙️ Feature/App addition
• 🪛 Bugfix
• ⚠️ Breaking change (fix or feature that would cause existing functionality to not work as expected)
• 🔃 Refactor of current code
• 📜 Documentation Changes

🧪 How Has This Been Tested?

Reproduced Renovate's own matchPackagePatterns migration and regex-matching logic (from lib/config/migrations/custom/package-rules-migration.ts and lib/util/string-match.ts) locally in Node, and confirmed the updated pattern correctly matches ghcr.io/homebridge/homebridge and correctly excludes docker.io/homebridge/homebridge, homebridge/homebridge, etc.

Also pulled the live tag list from ghcr.io/homebridge/homebridge (425 tags) and ran the existing versioning regex against all of them: 91 correctly parse as dated releases (newest: 2026-07-31), the remaining 334 (-ubuntu, alpha-*, beta-*, named branches, etc.) are correctly excluded.

📃 Notes:

Not claiming this fixes whatever caused the year-long gap in homebridge update PRs before the registry switch (last one merged 2025-07-28) — I don't have visibility into this org's Renovate run history to diagnose that. This just avoids a second, new break from the registry switch in trueforge-org/truecharts#50995.
