Update compiler version to 2024-07-19 (rust 1.81.0-nightly)

Hey there, really awesome tool, thank you for making it!

Just wanted to update this to Rust 1.81.0 (current stable) which my project is currently using.

According to https://releases.rs/docs/1.81.0, 1.81.0-nightly corresponds to nightly-2024-07-19. See the following output from cargo:

info: syncing channel updates for 'nightly-2024-07-19-aarch64-apple-darwin'
info: latest update on 2024-07-19, rust version 1.81.0-nightly (5affbb171 2024-07-18)

Since the channel has been nightly-2024-07-25 (newer) before, I think it's been wrong by accident. The page on https://releases.rs/docs/1.80.0 says "Released on: 25 July, 2024", but I think the date from "Branched from master on: 7 June, 2024" should be taken for the nightly string instead.

Thanks! However, I'm not sure what to do here... I mean: the current version is already more up-to-date than this one, although the counting is off. Might be worth "forgetting" about it and just make a 0.82 release when rust 1.82 will be released.

The 0.80.0 release then technically has an ABI mismatch, but given that the current scripts seem to run, doesn't sound like there has been any breakage.

For 0.81.0 (this PR) I don't see any reason why moving to the correct version (even though it's moving backwards) would be an issue.

Just tried this out, e.g. adding

clippy_utils = { git = "https://github.com/rust-lang/rust-clippy", tag = "rust-1.81.0" }

as a dependency works on the proposed 0.81.0 release, but

clippy_utils = { git = "https://github.com/rust-lang/rust-clippy", tag = "rust-1.80.0" }

won't on 0.80.0.
