chore: bump golangci-lint to 2.11.2

[arturaslcast]

to make it compatible with go 1.26.

temporary exclude gosec G118 which incorrectly detects the following code:

		ctx, cancel := context.WithCancel(t.Context())
		t.Cleanup(func() {
			cancel()
			watcher.Stop()
		})

as:

internal/informer/node_informer_test.go:308:36: G118: context cancellation function returned by WithCancel/WithTimeout/WithDeadline is not called (gosec)
		ctx, cancel := context.WithCancel(t.Context())
		                                 ^
