fix: correct matrix versions to match actual distribution support

- Fix k3s versions: v1.31.10, v1.32.6 (supported as patch versions)
- Fix kind versions: v1.31.9, v1.32.5 (distribution-specific patches)
- Fix EKS versions: v1.31, v1.32 (major.minor only, no patch versions)
- Remove base matrix dimensions, use include-only format
- Update documentation to reflect distribution-specific version requirements

Error resolution based on cluster creation API responses:
- EKS: does not support patch versions like v1.31.10 or v1.32.6
- kind: supports specific patches v1.31.9, v1.32.5 (not v1.31.10, v1.32.6)
- k3s: supports full patch versions v1.31.10, v1.32.6
