Naming mismatch in docker_compose.yaml

[ndahdah]

How to reproduce:

$ docker compose -f examples/vins_docker_compose.yaml up
->
[+] Running 1/1
✘ miluv Error 0.5s
Error response from daemon: pull access denied for miluv-vins, repository does not exist or may require 'docker login': denied: requested access to the resource is denied

Proposed solution:
Rename miluv-vins to miluv_vins in examples/vins_docker_compose.yaml.
