Pushed changes to this PR to shift all publishing shebangs to be bash

[mariannegoldin]

LGTM!

I'm sorry I'm a little confused why this PR is open. What was broken with /bin/sh? /bin/sh should exist on all unix-compatible systems, but /bin/bash shouldn't be guaranteed to do so (love the unix ecosystem). i understand we're using an ubuntu docker image but want to make sure i understand the problem :)

@nellshamrell was running into issues with using source file.sh over the WSL of Linux, and resolution was to update this shebang. I dont have the hardware to confirm that this was independent of the issue, and will need to defer explanation beyond this

[nellshamrell]

it did not work on WSL, and when I changed it it did work, that is my best explanation :)

[nellshamrell]

Just confirmed that is still the case on my system - this appears to be necessary for use with WSL
