This is the minimal PR which didn't run apply.sh. Please comment if you'd prefer that I run it to update the dockerfiles.

Thank you for the prompt feedback.

Bumping this.

I've built this image and scanned it with trivy

aa1c716f4b3d (alpine 3.20.1)

Total: 0 (UNKNOWN: 0, LOW: 0, MEDIUM: 0, HIGH: 0, CRITICAL: 0)

Looks great! Much better than any other redis image i've scanned with alpine or debian
