If both are supported (pretty sure they are), I'd prefer using .typos.toml over _typos.toml.

I just discovered that we could also use [workspace.metadata.typos] in the Cargo.toml file. I think that would me my preferred choice, unless you disagree

Not sure what to think of the config in Cargo.toml, really. For cargo plugins it makes sense to me, for more or less entirely language-agnostic tools like typos it feels a little weird. But it's nice to have one file less, I suppose.

huh, I guess I figured with the org name being crate-ci it was somewhat Rust-specific, but you're right, that there isn't much in it that is specific to Rust.

yeah, even two files less in this case :D
