Replaced #!/usr/bin/env python with #!/usr/bin/python

[AllRWeak]

Staring from Ansible 2.17.1 modules in this collection are unable the find the Python interpreter. According to This issue ansible/ansible#83603 and Ansible development guide https://docs.ansible.com/ansible/latest/dev_guide/developing_modules_documenting.html#python-shebang-utf-8-coding all modules should start with #!/usr/bin/python

This PR replaces #!/usr/bin/env python with #!/usr/bin/python in all modules to make sure they match with Ansible module format and fixes #508

This fix has also been tested on Ansible 2.17.0 to make sure it's also backwards compatible.
