Update README.md

[martinjost]

Changed description of valid version ranges for Release Notes. While the old one is technically correct, it is confusing, due to the overlapping version range.
Testing done

Submitter checklist

• [x ] Make sure you are opening from a topic/feature/bugfix branch (right side) and not your main branch!
• Ensure that the pull request title represents the desired changelog entry
• Please describe what you did
• [NA] Link to relevant issues in GitHub or Jira
• [NA] Link to relevant pull requests, esp. upstream and downstream changes
• [NA] Ensure you have provided tests that demonstrate the feature works or the issue is fixed

This is deliberate. Can your issue be resolved in a way that retains correct version ranges?
