Adding a Workflow for greetings to new issue

[aditiverma-21]

This workflow runs whenever a new issue or pull request is opened.
Greet User: It uses the actions-ecosystem/action-create-comment action to post a customized comment directly on the issue or pull request.
Personalized Message: The message greets the user by username and dynamically adjusts based on whether it’s an issue or pull request. It also includes a link to the contribution guidelines for new contributors.
Benefits of the Greeting Workflow

Improves User Experience
Encourages Quality Contributions
Reduces Common Questions

Ideally this approach is bad, as per guidelines raise all issue related to workflow and get level3 as this is repeated process
