chore: use variables in Rust format strings

Change this:

    format!("{}", foo)

into this:

    format!("{foo}")

Support for this feature was added in Rust 1.58 (see
https://github.com/rust-lang/rust/releases/tag/1.58.0) and in 1.67
clippy suggests about this. Because the new style seems to be where
the Rust ecosystem is going, I think Subplot should follow to avoid
being needlessly different from most other projects.
