Bug in postBuild shebang line

[she3o]

Bug description

The shebang line in postBuild generated by quarto use binder is:

#!/usr/bin/env bash -v

On mybinder.org, I get this log:

Step 62/67 : RUN ./postBuild
 ---> Running in 3084941ca008
�[91m/usr/bin/env: ‘bash -v’�[0m�[91m: No such file or directory
/usr/bin/env: use -[v]S to pass options in shebang lines
�[0m ---> Removed intermediate container 3084941ca008
The command '/bin/sh -c ./postBuild' returned a non-zero code: 127

Steps to reproduce

$ # git clone 'http://github.com/she3o/whyR'

$ quarto use binder
...

$ git add apt.txt postBuild runtime.txt
...

$ # Go to mybinder.org
# Paste Github URL
# press launch
# on step 62, the build fails

Expected behavior

binder images should be built successfully.

Actual behavior

Step 62/67 : RUN ./postBuild
 ---> Running in 3084941ca008
�[91m/usr/bin/env: ‘bash -v’�[0m�[91m: No such file or directory
