fix: Change shebang at the begining of a shell script (#24)

Changed the shebang in the script from `#!/bin/bash` to a more
portable `#!/usr/bin/env bash`. This modification aims to enhance
the script's portability across different operating systems.

Using `#!/usr/bin/env bash` allows the script to dynamically
locate the bash interpreter in the current environment, eliminating
potential issues associated with variations in the location of the
bash interpreter on different systems. Additionally, this adjustment
facilitates collaboration with environments where program paths may
differ.

The purpose of this change is to improve the script's portability
and minimize the need for manual updates to the bash interpreter
path in case of any future changes.
