Docker-Container: Style sheet error & Extending Documentation

Hi all,

i am trying to set up the latest sortinghat docker container on a server of ours and access it via remote.

To do that i followed in basic [your guide](https://github.com/chaoss/grimoirelab-sortinghat/tree/master/docker). As i need to access it via remote, i used the `-e 'SORTINGHAT_ALLOWED_HOST=localhost,127.0.0.1,IP_ADDRESS` option .

However, when accessing the webpage (Port 8000 in this case) the Browswer Extension shows the following errors:
`Refused to apply style from 'http://[IP-ADDRESS]:8000/identities/css/chunk-vendors.8624f262.css' because its MIME type ('text/html') is not a supported stylesheet MIME type, and strict MIME checking is enabled.
Refused to execute script from 'http://[IP-ADDRESS]:8000/identities/js/chunk-vendors.870fdbfd.js' because its MIME type ('text/html') is not executable, and strict MIME type checking is enabled.
Refused to apply style from 'http://[IP-ADDRESS]:8000/identities/css/app.b1eaa349.css' because its MIME type ('text/html') is not a supported stylesheet MIME type, and strict MIME checking is enabled.
Refused to execute script from 'http://[IP-ADDRESS]:8000/identities/js/app.0a23ef75.js' because its MIME type ('text/html') is not executable, and strict MIME type checking is enabled.
`

However, the docker outputs at the same time:

`[pid: 16|app: 0|req: 1/1] [[IP-ADDRESS] () {40 vars in 801 bytes} [Thu Nov 2 08:04:00 2023] GET / => generated 851 bytes in 671 msecs (HTTP/1.1 200) 6 headers in 180 bytes (1 switches on core 0)

`

That leads me to two questions/requests:

1. Is that an configuration error on my side (am i missing an option) or is that an SortingHat Error
2. It would be nice to have an extended documentation of all the available options. Figuring out the SORTINGHAT_ALLOWED_HOST Option with the right `,` separator took me way to long. Having both a list of available options & what they do and a separated usage guide for the Dev- and Prod-Variant would be really helpful and save a lot of time for users.

Can you help me there?

Thank you very much

Stefan
