OSDOCS-21318: Document excludeSubnets as CIDR-only

[JoeAldinger]

Summary

• Corrects the excludeSubnets row in the OVN-Kubernetes network plugin JSON configuration table.
• Docs previously said bare IP addresses were accepted; the parser and CRD require standard CIDR notation with a prefix length (use /32 or /128 for a single address).

Jira

https://redhat.atlassian.net/browse/OSDOCS-21318

Versions

4.21 (cherry-picks may be needed for other enterprise branches / main)

Test plan

• Confirm rendered Multiple networks → Secondary networks table shows CIDR-only wording for excludeSubnets
• Aligns with ClusterUserDefinedNetwork / primary network docs that already require CIDR notation
