fix(docker): set addr flags to 0.0.0.0 in entrypoint file

[MSevey]

When using port forwarding in docker, you need to use the any address interface 0.0.0.0 otherwise you would be able to communicate to the server inside the container.

This PR updates the entrypoint.sh file to set the RPC and Gateway addresses to 0.0.0.0 so that developers can properly communicate to the node when exposing ports, for example -p 26658:26658.

apart from length, is there any other reason to wrap it in COMMAND ?

nope, just DRY'ing up the code a little.

is this a known NDF in the test suite?
