Use a `rust-toolchain.toml` file?

This is something I've gotten in the habit of doing in my Rust projects, to help lock the development environment to a specific Rust version.

As an added bonus, We can drop the CI steps that setup the preferred Rust version, as the built-in cargo executable in the actions runners should automatically download and use the specified rust version.

OTOH that could make someone like me accidentally( more like undesirably)¹ download a whole new toolchain just for one project so unless we have a really strong sense of backward compatibility and reproduciblity, it could be better following what the latest stable toolchain is.

1. it's not like it's not completely uncontrollable from my end, just comment out channel is what I normally do but that is a mild inconvenience you know.. ↩

🤔 Yeah, I can see how being forced to download a new toolchain for a single project could be annoying. I do think that a rust-toolchain.toml file is a bit more friendly for contributors who are beginners in Rust or programming in general, as it eliminates the question of "what Rust version are you on?" E.g. There's less of a chance that a new contributor wouldn't be able to compile onefetch due to their version being to low.
