Corretto 8 AL2023 JDK and JRE are build from the same Dockerfile

[gietschess]

Describe the bug

Images with tags 8-al2023-jdk and 8-al2023-jre are both build from the 8/jdk/al2023/Dockerfile.

To Reproduce

Tags share the same SHA.
See https://hub.docker.com/layers/library/amazoncorretto/8-al2023-jdk and https://hub.docker.com/layers/library/amazoncorretto/8-al2023-jre

Example output from the 'Generate tags for pr' actions:

Tags: 8-al2023, 8u472-al2023, 8-al2023-jdk
Architectures: amd64, arm64v8
Directory: 8/jdk/al2023

Tags: 8-al2023-jre, 8u472-al2023-jre
Architectures: amd64, arm64v8
Directory: 8/jdk/al2023

Expected behavior

As described in the README.md i'd expect the 8-al2023-jre tagged image to be build from the existing 8/jre/al2023/Dockerfile.
