@SlyCaptainFlint Take a look at this whenever you get time. (P.S. mentioned you since you recently refctored other actions)

Example of greet message (though, not added by this action):
#37488 (comment)

1. What else do we need to add in the greet message? (I would say; short, simple & sweet 😊)
2. Do we need to mention the contributor ? (FYI: This would add extra complexity)
3. What should be removed from current message?

Cc: @cortinico WDYT? 🙂

This week we've seen a lot of "First Time Contributors"
Chain React 👍

Cc: @cipolleschi do you think having this action would benefit...?

1. What else do we need to add in the greet message? (I would say; short, simple & sweet 😊)

The only thing I would add is a note to check what Danger is reporting, as people tend to ignore it. Other than that, I believe we're good to go 👍

Done.
P.S. I'm not used to multiline strings syntax of yaml especially in actions so, may be you can validate; if it'll work with proper formatting on GitHub.

Great job! I personally love that, as it may save us some repetitive messaging!

I left a small comment, which I am not super sure about too, tbh. XD

I think that, with the | operator, we can remove the " at the beginning and end of the string.

Sure. Let's go with your suggestion. 😉👍
I hope the 1st contributor seeing this in action will be happy and most importantly, the msg formatting will be proper.

Done. 🚀🤞

@cipolleschi looks like you didn't import the latest changes, so the merged commit still has those "s 🙂
