As my pull request wasn't build automatically, I created a testing version on Docker Hub that includes the DomainOffensive plugin from georgeto. (Thanks to Knoxell for showing me how to do this!)

version: "3"
services:
  app:
    image: 'dfs90/nginx-proxy-manager-do-de'
    restart: unless-stopped
    ports:
      - '80:80'
      - '81:81'
      - '443:443'
    volumes:
      - ./data:/data
      - ./letsencrypt:/etc/letsencrypt

I can confirm that this commit works; I was able to successfully create a Let's encrypt wildcard certificate for DomainOffensive (do.de) with my build mentioned above.

This is an automated message from CI:

Docker Image for build 3 is available on DockerHub as jc21/nginx-proxy-manager:github-pr-2327

Note: ensure you backup your NPM instance before testing this PR image! Especially if this PR contains database changes.

Successfully tested the merged "develop" build. Thanks for merging!
