Add GitHub Action to Welcome First-Time Contributors

[shivasankaran18]

Feature Request 🛍️

We want to improve our onboarding experience for new contributors by automatically welcoming first-time issue reporters and pull request creators with a friendly message.

Use Case

When a user opens their first issue or first pull request, the GitHub Action should detect that it’s their first contribution to the repo and post a welcome comment. This message can direct them to:

• Contribution guidelines
• Community support channels (e.g., Discord,)

Possible Solution

A GitHub Action using actions/github-script can be used .. We can use the GitHub GraphQL API to determine whether it’s a user's first-ever issue or PR
