fix: Align instrumented-tests job condition with workflow-level environment variable

- Update job condition from 'vars.RUN_INSTRUMENTED_TESTS == true' to 'vars.RUN_INSTRUMENTED_TESTS != false'
- Fixes issue where instrumented tests job never ran despite workflow env being set to true
- Job-level condition now matches workflow-level environment variable logic
- Removes unnecessary pull_request condition (redundant with workflow triggers)

This ensures instrumented tests actually execute when the environment variable
evaluates to true at the workflow level.
