Make explicit rust version requirement

[wu-sheng]

I was facing Rustc error as 1.65+ is required. And I find out there is no rust 1.65 on brew(https://formulae.brew.sh/formula/rust).

So, I have to follow Rust release blog(https://blog.rust-lang.org/2022/11/03/Rust-1.65.0.html), and use rustup update stable command to upgrade the rust version

Do you know how to promote brew to update the rust version?

I tried brew upgrade rust, but it didn't work. Because there isn't 1.65 actually here,

> brew upgrade rust
Running `brew update --auto-update`...
==> Auto-updated Homebrew!
Updated 1 tap (homebrew/core).

You have 15 outdated formulae installed.
You can upgrade them with brew upgrade
or list them with brew outdated.

Warning: rust 1.64.0 already installed

The brew version should be managed by the rust team, actually. They registered this project.

Now the rust version in brew has updated to 1.65.
