Port 8448 is not enabled from inside the Docker container

Background information

• Dendrite version: Dendrite 0.14.1+40bef6a
• SQLite3 or Postgres?: Postgres
• Running in Docker?: Docker
• go version: go1.22.2

Description

• What is the problem: Port 8448 is not enabled by default from inside the Docker container. The example docker-compose.yml contains

ports:
      - 8008:8008
      - 8448:8448

Despite that, the port 8448 does not listen for anything. To test it, I launched a shell from inside the docker container: docker exec -it <ID> /bin/sh and this is the output of netstat -tuln:

Proto Recv-Q Send-Q Local Address           Foreign Address         State       
tcp        0      0 127.0.0.11:45021        0.0.0.0:*               LISTEN      
tcp        0      0 :::8008                 :::*                    LISTEN      
udp        0      0 127.0.0.11:41453        0.0.0.0:*     

As you can see, 8008 is correctly listed; 8448 is not.

• Who is affected: Every system mantainer using the latest Docker image I guess
• How is this bug manifesting: No response on 8448

Steps to reproduce

• Download the .yml file from here
