Update GitHub Actions workflow for YARRML integration

[marvinm2]

Update GitHub Actions workflow to use YARRML + Python pipeline while preserving all quality control.

Requirements

• Install YARRML tools (RMLMapper, YARRML parser) in GitHub Actions
• Update workflow to use YARRML → Python enrichment pipeline
• Maintain gene mapping, chemical enrichment, and validation steps
• Preserve automatic Turtle File Quality Control integration

Pipeline Steps

1. YARRML core XML-to-RDF mapping
2. Python gene mapping and precision filtering
3. Python chemical identifier enrichment via BridgeDb
4. Quality validation and file generation

Dependencies

• Completed YARRML mappings from issue Design YARRML mapping strategy for AOP-Wiki structure #61
• Working combined pipeline from issue Implement hybrid YARRML + Python post-processing approach #62

Success Criteria

• Workflow generates equivalent RDF files with new approach
• All quality enhancements preserved (gene filtering, chemical IDs)
• Performance remains within acceptable limits
