Greptile Summary

This PR bumps the Network Operator documentation from v26.4.0 to v26.4.1, updating container image digests, version substitution variables, Helm chart defaults, example YAML files, and the platform support matrix to reflect new Kubernetes 1.36 and OpenShift 4.22 support.

• All container image SHA256 digests and version tags were updated from network-operator-v26.4.0 to v26.4.1; the STIG FIPS DOCA-OFED driver was additionally bumped from suffix -0 to -1.
• docs/platform-support.rst was updated to extend Kubernetes support to 1.36 and OpenShift to 4.22, including in the GPUDirect RDMA sub-table.
• The 26.4.1 release notes entry was added covering CVE fixes, OpenShift 4.22, Kubernetes 1.36, RHEL 9.8, and RHEL 10.2 support — but the OS support table was not updated to include RHEL 9.8 or 10.2 as validated rows.

Confidence Score: 4/5

Safe to merge with the caveat that the platform support table omits the newly announced RHEL 9.8 and 10.2 rows.

The release notes for 26.4.1 explicitly call out added support for RHEL 9.8 and RHEL 10.2, but the OS support table in docs/platform-support.rst was not updated to include those rows. Users checking the support matrix will not see those OS versions listed, which contradicts the official release notes.

docs/platform-support.rst — the OS support table needs RHEL 9.8 and RHEL 10.2 rows added to match the release notes.
