PULL REQUEST CHECKER WORKFLOW AUTOMATION 🚀

[amiya-cyber]

Description: We need to create a GitHub Actions workflow that automates the validation of pull requests (PRs). This workflow will ensure that all PRs meet the following criteria before being merged:

PR Description Check: Every PR must have a description. If the description is missing, the PR should fail the check.

Issue Reference Check: The PR description must include an issue reference in the format Fixes #. If the PR is not addressing an existing issue, it should mention Fixes #NEW as a placeholder.

Acceptance Criteria:

A GitHub Action workflow is triggered on PR events (opened, edited).
The workflow checks the PR body for:

A non-empty description.
The presence of Fixes # or Fixes #NEW.
If the criteria are not met:

The workflow should fail and return clear error messages.
If the checks pass:

A confirmation message is outputted.

Expected Output:

1. Error message if the PR description is missing.
2. Error message if the issue reference is missing or incorrectly formatted.
3. Success message when all checks are satisfied.
