Fix GitHub Actions workflow to use Python yq instead of Mike Farah yq

Update dispatch.yaml workflow to use Python-based yq (jq-compatible syntax)
instead of Mike Farah's yq. This fixes the "Unable to parse steps" issue
in E2E test report processing by using consistent yq syntax across environments.

Changes:
- Install python3-pip and yq via pip instead of downloading binary
- Remove 'e' flag from yq commands (Mike Farah syntax -> Python syntax)
- Add tr -d '"' to clean quoted output from Python yq
