This changes the scripts to use /usr/bin/env and system PATH to find Bash.
Although massively widespread, IIRC Bash is not part of POSIX proper. Therefore, unlike /bin/sh, it can't truly be relied on to be present under /bin [^0]
[^0]: For example, on NixOS, sh is the only thing in /bin, and env is the only thing in /usr/bin. So, to find the bash executable, /usr/bin/env looks on the system path and resolves to e.g. /nix/store/aw76ql7s2n8gl02swkf2i3bdn9m7qxvh-bash-interactive-5.2-p15/bin/bash :sweat_smile:
