solid-test script uses bash and doesn't work in official docker image

The solid-test script has #!/usr/bin/env bash for a shebang. However, the docker image provided at nodesolidserver/node-solid-server only comes with sh, not bash.

This means that if you try and run solid-test using the docker image, you get:

/opt/solid $ /usr/local/lib/node_modules/solid-server/bin/solid-test
env: can't execute 'bash': No such file or directory

It seems that this script is so simple that it should be possible to just use sh, at least on linux. I don't know if sh on macos is now zsh, or a borne compatible shell.

Comienza con el punto de entrada solid-test en bin/solid-test, al que hace referencia el issue, e inspecciona sus requisitos de shell. Ejecútalo en la imagen oficial nodesolidserver/node-solid-server; se considera terminado cuando el comando se ejecuta allí sin requerir un ejecutable bash no disponible y se conserva su comportamiento existente.
