Konflux release-data RPA updates

Goal

Given a target RHDH version (for example 1.9.7), update the matching stream ReleasePlanAdmission files under config/stone-prod-p02.hjvn.p1/product/ReleasePlanAdmission/rhdh/ so tag values use the new patch version, then push a branch and open a GitLab merge request.

Prerequisites

• Local clone of konflux-release-data
• git, glab (GitLab CLI authenticated to gitlab.cee.redhat.com)
• Push access to origin (git@gitlab.cee.redhat.com:releng/konflux-release-data.git)
• Optional: tox when using --validate

Run from the user's konflux-release-data checkout — never assume a fixed path. Pass --repo-dir or cd into the target folder before invoking the script.
