MySQL8 incompatible with RedHat UBI 8.3

Summary

When MySQL is built with RedHat UBI 8.3, the container fails to run. Running with RedHat UBI 8.2 works.

Steps to reproduce

• docker build --build-arg BASE_TAG=8.3 -t mysql:dev .
• docker run --rm -it mysql:dev

What is the current bug behavior?

After running, the logs will show: Error: Unknown setting - enforce_for_root

What is the expected correct behavior?

After running, the logs will reach this line: [Entrypoint] GENERATED ROOT PASSWORD: ****

Possible fixes

Unsure where the issue is, but a clue is that using RHEL UBI 8.2 as a base image does NOT experience the problem.
