Binder no longer building

Hello,

I am trying to try out this repo through myBinder, but I get this error after clicking the link in the README:

Step 47/52 : RUN ./binder/postBuild
 ---> Running in 9d02d8a28ab5
Traceback (most recent call last):

The command '/bin/sh -c ./binder/postBuild' returned a non-zero code: 1

It looks like this commit yesterday is what is causing the problem: https://github.com/Accessible-Data-and-Code/jupyterlab-ide/commit/d49261e8b887631d40543209b3f8d2a05ce48b1d . That adds a dict to the dependencies array which isn't accepted by the subprocess.run in ./binder/postBuild. I'm not totally sure what the proper solution is here, but maybe just flattening the array or using a separate one?
