Unclear intent of Cargo.toml sorting

[scop]

Describe the bug

dprint-plugin-toml version: 0.7..0

Per cargo.applyConventions (default true) current docs, "Whether to apply sorting to a Cargo.toml file."

It's kind of vague what kind of sorting this actually means, but at least for the example Cargo.toml below, the sorted result is neither alphabetical nor the one for the keys listing at https://doc.rust-lang.org/cargo/reference/manifest.html#the-homepage-field

I don't personally have that strong opinion about the format, but if I were to start a tool like this, I'd make it sort keys the same as they are in the above manifest doc.

But if the current sorting is there to stay and intentional, perhaps amend the docs a bit about what kind of sorting to expect, even if it's just "Whether to apply opinionated sorting to a Cargo.toml file." (emphasis just to highlight).

It should align with: https://github.com/rust-lang/rust/blob/07b5eeebc948743eaadb32a83d23931fd8854fe8/src/doc/style-guide/src/cargo.md

FYI I sent a PR upstream that would sync the doc I was using as a reference with the style guide this plugin is using, and upstream seems to indicate the style guide ordering is not ready for use yet, rust-lang/cargo#15285 (comment)
