docs: Remove broken badge and fix docker-compose snippet

[djquan]

1.) This PR removes the microbadger badge. It's not resolving, and the project is shutdown:

2.) Remove a trailing space. I think this is causing the snippet to now show up as expected on the quickstart guide with image and volumes being on the same line:

3.) Adjusts the indentation of the docker-compose snippet

Hi, on the webpage, the docker-compose snippet is broken. It is supposed to be fixed and if I look to c33bb05, it "looks" fixed, but nevertheless is still displayed wrong

[JMoVS]

Possibly adding a new line between

=== "docker-compose.yml"
<new line here>
    ```yaml

could help - but I'm not sure

[piksel]

@JMoVS the docs have not been deployed since the fix. that is usually done every release.

ah okay, then it makes sense ;-)
