Update Ubuntu/Debian installation instructions to use Signed-By option (#26906)

Browse Source 
The use of `apt-key` to install has also been removed as it is now deprecated
and will be last available in Debian 11 and Ubuntu 22.04.

Also updates the Docker repository setup instructions in container-runtimes.md,
to now refer to the respective instructions at https://docs.docker.com/engine/install/
which has already made the move to use the signed-by option.

1. Update the `apt` package index and install packages needed to use the Kubernetes `apt` repository:
```shell
sudo apt-get update
sudo apt-get install -y apt-transport-https ca-certificates wget
```
2. Download the Google Cloud public signing key:
```shell
sudo wget -O /usr/share/keyrings/kubernetes-archive-keyring.gpg https://packages.cloud.google.com/apt/doc/apt-key.gpg
```
3. Add the Kubernetes `apt` repository:
```shell
echo "deb [signed-by=/usr/share/keyrings/kubernetes-archive-keyring.gpg] https://apt.kubernetes.io/ kubernetes-xenial main" | sudo tee /etc/apt/sources.list.d/kubernetes.list
```
4. Update `apt` package index, install `kubelet`, `kubeadm` and `kubectl`, and pin their version:
