Upgrade Go packages to fix CVEs (#1114)

## Proposed Changes


### 1. Root Module (github.com/google/kf/v2)
Upgraded github.com/docker/docker replacement version from
v20.10.24+incompatible to v28.5.2+incompatible in root

go.mod
 (resolves GO-2025-3829).
Refactored Term/Console Packages: The docker/docker/pkg/term dependency
was removed in newer Docker CLI/engine versions. The importing code was
refactored to use the modern alternative github.com/moby/term:

- ssh.go
- term.go
- resize.go
- term_writer.go

### 2. Submodule first_party/k8s-stateless-subresource
Upgraded google.golang.org/protobuf to v1.33.0 (resolves GO-2024-2611).
Upgraded google.golang.org/grpc to v1.56.3 (resolves GO-2023-2153).
Upgraded golang.org/x/oauth2 to v0.27.0 (resolves GO-2025-3488).
Upgraded github.com/golang/protobuf to v1.5.4 for compatibility.
### 3. Operator Module (github.com/google/kf/v2/operator)
Upgraded Go Toolchain from go1.20 to go1.25.0 in 

operator/go.mod
.
Upgraded golang.org/x/net to v0.56.0 (resolves GO-2026-5026,
GO-2026-4918, and GO-2024-2687).
Upgraded github.com/google/go-cmp to v0.6.0 to resolve comparisons
clashing with new Go context internals.
Added operator/tools.go: Pinned code-generator packages
(k8s.io/code-generator) and mock generation frameworks
(github.com/golang/mock/mockgen) so they are correctly vendored.
Refactored Tests:
Modified 

fake_owner_injector_test.go
to use cmpopts.IgnoreFields to skip comparing the Ctx field (containing
context internals), resolving panics under Go 1.25+.
### 4. Build & Codegen Fixes
Fixed operator/hack/update-codegen.sh:
Resolved knative.dev/hack and k8s.io/code-generator script paths from
the Go mod cache dynamically to support headless execution and prevent
dependency package resolution errors during compilation.
Stubbed helper libraries operator/scripts/shared/library.sh and root
hack/library.sh to allow codegen scripts to execute correctly.
Re-generated Client Fakes & Deepcopy API Objects under the operator's
versioned clientset packages.
