Pull request overview

This PR aims to restore/improve MarkLogic crash stack trace generation for the (root) UBI-based images by ensuring required debugger/runtime dependencies remain in the image, and by documenting the required container capability (SYS_PTRACE) in the README.

Changes:

• Stop removing Python-related packages in the marklogic-server-ubi image cleanup step so debugger stack traces can be generated.
• Expand UBI8/UBI9 dependency images to explicitly install gdb-related runtime dependencies.
• Update README examples and add a new section describing how to enable stack trace generation via --cap-add=SYS_PTRACE.

Looks good, but I have a small concern regarding the basic docker-run examples. Maybe we can check with PO on this.

We need to make sure the pipeline is green before the merge.

Looks good to me. We can wait for pipeline to be green and merge
