chore: fix typos

[Shresth79]

What was wrong?

There was a typo in the class name PersistantSocket in web3/providers/ipc.py. The correct spelling should be PersistentSocket (with an 'e' instead of 'a').

How was it fixed?

Fixed the typo by renaming the class from PersistantSocket to PersistentSocket throughout the file.

This is a breaking change and this provider has been deprecated and will be removed. I'm going to close this.

Actually, I apologize on both of my comments and will re-open 😅.

I was under the impression the PersistantSocket was for the old WebSocket provider (now, LegacyWebSocketProvider). I don't think we changed this because it seems like a breaking change but it actually sets the socket on a private, underscored _socket which technically means it can and should be corrected - as this is not a public API.

I'm going to let others get eyes on this to make sure I'm not missing anything but I think this is a fine change to make, and I believe it to be a non-breaking change. Do you want to add a newsfragment for this? If not we can. And thanks for the PR!

@kclowes If you're good with this as non-breaking I can add a newsfragment and merge 👀

Yep, LGTM!
