Greptile Summary

This PR bumps all Network Operator component versions and SHA256 digests from v26.4.0 to v26.4.1, updates the DOCA-OFED driver from doca3.4.0-26.04-0.8.6.0-0 to doca3.4.1-26.04-1.1.0.0-1, and extends platform support to include Kubernetes 1.36, OpenShift 4.22, RHEL 9.8, and RHEL 10.2.

• Version variables in vars.rst, Helm defaults in helm.rst, and all ten examples/processed/** YAML manifests are updated consistently to network-operator-v26.4.1.
• images-sha256.rst now includes new RHEL 9.8 and RHEL 10.2 DOCA driver image entries; the DOCA-OFED Ubuntu section was simplified (kernel-specific variant tags removed in favor of generic OS-level tags).
• platform-support.rst main OS table adds RHEL 10.2 and 9.8 and extends K8s/OCP ranges, but the GPUDirect RDMA sub-table was not updated to match — RHEL 9.8 and 10.2 are still absent from that table.

Confidence Score: 4/5

Safe to merge after fixing the GPUDirect RDMA table — one doc table was not updated to match new RHEL OS coverage.

The main platform support table, DOCA image digest table, and release notes all correctly document RHEL 9.8 and 10.2 support, but the GPUDirect RDMA sub-table at line 419 of platform-support.rst still lists only Red Hat Enterprise Linux 10.0 / 9.6 / 9.4. This leaves two tables in the same file disagreeing about which RHEL versions are supported for GPUDirect workloads, which will mislead users on those OS versions.

docs/platform-support.rst — the GPUDirect RDMA support table needs its RHEL row updated to include 10.2 and 9.8.
