Update futures to 0.3.32

[dinocosta]

As part of the work that is being developed for the Project Panel's Undo & Redo system, in https://github.com/zed-industries/zed/tree/5039-create-redo , we're implementing an asynchronous task queue which simply receives a message with the operation/change that is meant to be carried out, in order to ensure these run in a sequential fashion.

While trying to use futures_channel::mpsc::Receiver, it was noted that recv method was not available so this Pull Request updates the futures crate to 0.3.32, where it is available.

This version also deprecates try_next in favor of try_recv so this Pull Request updates existing callers of try_next to use try_recv, which was mostly updating the expected return type from Result<Option<T>> to Result<T>.

I’ve updated this branch with ‎⁠main⁠, so it needs a fresh approval. I had already spoken with @benbrandt, who had already approved these changes, and agreed to merge this today so it can go into the next Nightly. That will give us a bit more time to test before it lands in Preview.

I’ll go ahead and merge now, but please do take another look at the updated changes when you get a chance, @benbrandt. Thanks! 🙇
