ADD: Automated Greeting Workflow

[samyak-aditya]

Description: I propose to implement a new GitHub Actions workflow named "Greetings," which automatically greets users who open new issues or pull requests in this repository.

Key Features:

• Automatic Greeting: Users will receive an immediate acknowledgment when they create an issue or pull request. The messages are:
  • For Issues: "👋 Thank you for raising an issue! We appreciate your effort in helping us improve. Our team will review it shortly. Stay tuned!"
  • For Pull Requests: "🎉 Thank you for your contribution! Your pull request has been submitted successfully. A maintainer will review it as soon as possible. We appreciate your support in making this project better."

Hey @Devamani11D Please assign this task to me

Hey @samyak-aditya , Thank you for your interest in contributing to the project!! This idea is very good!! But Can you also please have a look at issue #14 and see if they are related. If so i can assign the issues to both of you. And you both can work on it.
