Request to add a github action

[Jassi10000-zz]

This is an awesome and an engaging repository , plus due to hacktoberfest'21 many open source enthusiasts ( preferably students who are first time contributors ) open issues and PRs which eventually help repo to grow
I think there should be a github action to welcome contributors on their each issue and PR so as to make repository more interactive

If you love the idea , please assign this to me
