Docs: Remove all enclaver invocation

[robszumski]

Since the container image already contains the enclaver run command, we can remove it from any docker run instances:

$ docker run \
    --rm \
    --detach \
    --name enclave \
    --volume /var/run/docker.sock:/var/run/docker.sock \
    --device=/dev/nitro_enclaves:/dev/nitro_enclaves:rw \
    --port 443:443 \
-   us-docker.pkg.dev/edgebit-containers/containers/enclaver:v0.1.0 run \
    us-docker.pkg.dev/edgebit-containers/containers/no-fly-list-enclave:latest
