[FEATURE] Socket-proxy Allow list Regex

Is your feature request related to a problem? Please describe. While Implementing Tinyauth together with Socket-proxy I did some Debugging on the API Calls to Allow only those needed for Tinyauth.

services:
  tinyauth:
    image: ghcr.io/steveiliop56/tinyauth:v4
    container_name: tinyauth
    environment:
      - DOCKER_HOST=tcp://dockerproxy:2375
    labels:
      - 'socket-proxy.allow.get=/v1\..*/(version|containers/.*|events.*)|/_ping'
      - 'socket-proxy.allow.head=/_ping'

Describe the solution you'd like Maybe Implement it as an Example in the Docs to help others with the same case. If you would like I can try to make an PR for the Docs, just let me know what you want.
