Coding standard & Site configuration

Problem/Motivation

1: Replace README.txt with README.md

We could be using README.md instead of README.txt to make use of the nicer rendering via markdown.

Now that we've moved to GitLab, we should probably use Markdown instead of plain .txt files for our documentation.

Follow this pattern

README.md → template.

2: Hook_help() function missing from .module template.

In Drupal, the hook_help function is used to provide help documentation for your custom module. This documentation is displayed on the Help page of your Drupal site, making it accessible to administrators and users.

3: Module configuration missing on module Extend page

Note: I have created a patch for Site configuration and hook_help() function
