chore: deprecate void crate

[hanabi1224]

Description

The void crate provides a Void type that is conceptually equivalent to the never type(!). This PR tries to remove void crate from the dependency tree by replacing void::Void with std::convert::Infallible that will eventually become an alias of the never type(!)

This enum has the same role as the ! “never” type, which is unstable in this version of Rust. When ! is stabilized, we plan to make Infallible a type alias to it:

Notes & open questions

Change checklist

• I have performed a self-review of my own code
• I have made corresponding changes to the documentation
• I have added tests that prove my fix is effective or that my feature works
• A changelog entry has been made in the appropriate crates

Hi, and thanks for this! ❤️

Might want to update the Cargo.toml to bump the versions on them :)

EDIT: And changelogs

Thanks for the reminding Darius, and I am sorry I didn't state explicitly why I moved ahead without asking for it.
I think in this case it's mostly redundant since it's only a dependency that we stop using, wdyt?
