Bumps async-tungstenite so it unifies with the version selected by Zed, and ensure we don't use openssl

As and FYI, when I try to build off of latest main in zed repo (running Windows 11) as of today, I get this error:

cargo build --release

This commit where it was added that zed points to this branch zed-industries/zed@27a413a

I changed the dependency back to the prior version before the above commit and it is building fine (at least got past the above error I was seeing).
