fix: GitHub Actions workflows semantic errors

Fixed critical semantic and logic errors in auto-version and Docker workflows:

Auto-version.yml fixes:
- Removed duplicate echo statements for should_build_docker output
- Fixed malformed if/else structure (else after else)
- Removed redundant conditional blocks for docker: prefixes
- Cleaned up duplicate lines in summary generation

Build_and_publish_docker.yml fixes:
- Replaced hardcoded 'patrykiti' with dynamic ${{ github.repository_owner }}
- Enhanced regex pattern to support underscores in Docker tags: [a-zA-Z0-9\._-]*
- Fixed sed patterns for dynamic repository owner detection

These changes ensure workflows execute correctly and support any repository owner.
