Cannot make on some systems (including Guix)

[ispringle]

When attempting to build this project I get the following error:

ian@voltaire ~/git/hub/ProtonMail/proton-bridge$ make build-nogui
cd ./utils/ && ./credits.sh bridge
/gnu/store/3jhfhxdf6v5ms10x5zmnl166dh3yhbr1-bash-minimal-5.1.16/bin/sh: ./credits.sh: /bin/bash: bad interpreter: No such file or directory
make: *** [Makefile:353: internal/bridge/credits.go] Error 126

Expected Behavior

I expect that the make file would at least start successfully and all shell scripts should either exit successfully or give an error relating to deps.

Current Behavior

Fails to run the associated shell files.

Possible Solution

The shebangs need to be updated to /usr/bin/env bash as not all environments provide bash at /bin.

There is already a PR (#327) in the works for this, although it's 2 years old and might need to be updated and surely needs to pull in master. Honestly might just be easier to run sed off the current master instead of trying to update this PR.

Steps to Reproduce

1. Use an environment that does not provide bash at /bin
2. Run make
3. Feel sad

Version Information

3.15.1

Context (Environment)

Guix

Detailed Description

Write all the shebangs from #!/bin/[shell] to #!/usr/bin/env [shell].
