Greptile Summary

Updates the Network Operator 26.7 catalog entry to the synchronized rc.2 release and advances its corresponding DOCA driver image.

• Changes the Network Operator chart version to v26.7.0-rc.2.
• Changes the shared component tag to network-operator-v26.7.0-rc.2.
• Changes the DOCA driver tag to doca3.5.0-26.07-0.7.1.0-0.

Confidence Score: 5/5

The PR appears safe to merge because the synchronized release coordinates are internally consistent and no actionable failure was identified.

The updated chart and component versions remain paired, the DOCA driver pin follows the same catalog update path, and existing repository validation enforces the relevant release-line and staging-artifact invariants.
