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.

从 issue 引用的 bin/solid-test 中的 solid-test 入口点开始，并检查其 shell 要求。在官方 nodesolidserver/node-solid-server 镜像中运行它；当 command 能够在那里运行而无需依赖不可用的 bash 可执行文件，并且其现有行为得到保留时，即视为完成。
