Add k8s and openshift dependency groups to dependabot

[sebrandon1]

Summary

• Add k8s group to consolidate k8s.io/* and sigs.k8s.io/* dependency updates
• Add openshift group to consolidate github.com/openshift/* dependency updates
• Update go-dependencies group to exclude k8s and openshift patterns to avoid duplicate grouping

This reduces noise from individual dependency update PRs by grouping related Kubernetes and OpenShift library updates together.

Walkthrough

The pull request modifies the Dependabot configuration to establish two new dependency update groups—k8s and openshift—targeting Kubernetes and OpenShift-related packages. Corresponding exclude patterns are added to the go-dependencies group to prevent overlapping updates for these namespaces.

Changes

Cohort / File(s)	Summary
Dependabot configuration \.github/dependabot\.yml	Adds two new dependency groups (k8s and openshift) with patterns for k8s.io/*, sigs.k8s.io/*, and github.com/openshift/*. Excludes these patterns from the go-dependencies group to segregate their update handling.

12-15: LGTM!

The k8s group correctly targets Kubernetes dependencies with appropriate glob patterns for k8s.io/* and sigs.k8s.io/* namespaces. Group positioning ensures these patterns match before the catch-all go-dependencies group.

---

16-18: LGTM!

The openshift group correctly targets OpenShift dependencies with an appropriate glob pattern for github.com/openshift/* namespace.

---

22-25: Configuration is correct. The exclude-patterns in the go-dependencies group properly prevent overlap with the k8s and openshift groups, ensuring packages are grouped only once. YAML syntax is valid and Dependabot will parse this configuration correctly.
