Add the drop combinator

[drewolson]

This is syntactic sugar for cases where you want to throw away the result of a monadic do. You can now write use <- drop(p) rather than use _ <- do(p).

Hey, thanks for taking the time to contribute!!

I like your drop combinator, I come up against use _ <- do(...) quite often haha.

Would you consider changing its implementation to use seq instead? It's unlikely we'll change seq, but if we did want to improve its behavior somehow then it'd be nice if drop got that improvement as well. And I've heard gleam is getting a function-inlining optimization at some point soonish, so it wouldn't be much slower.

I pushed an update to use seq. I've also (I think) fixed the github action by changing the gleam check command. Let me know if you'd like me to split these commits.

I don't fully understand the github action change but I'll accept it because I don't care too much about that formatting check.

Using lazy there was very smart, I didn't think of that! Great work.

Thank you for taking the time to contribute!
