test: add failing tests for updateSections force parameter

Add three tests for the upcoming force parameter feature:
1. Test that ifMatch is required when force is not set
2. Test that force=true bypasses ifMatch requirement
3. Test that valid ifMatch works without force

These tests are expected to fail until the force parameter
is implemented in updateSections.
