chore: drop k8s timeout in the default kubeconfig

(This is not user-facing, but rather internal use of the kubeconfig in
the tests/inside the machine).

This was added 4 years ago as a workaround, but instead of a global
timeout we should rather use contexts with timeouts/deadlines (and we
do!).

Setting a global timeout breaks streaming Kubernetes pod logs.
