Update rstar-benches geo dependency

[michaelkirk]

• [x] I agree to follow the project's code of conduct.

• [n/a] I added an entry to rstar/CHANGELOG.md if knowledge of this change could be valuable to users.

This fixes an error like:

error[E0275]: overflow evaluating the requirement ~/.cargo/registry/src/index.crates.io-6f17d22bba15001f/geo-0.24.1/src/algorithm/map_coords.rs:855:69: 855:72]: Fn<(geo_types::Coord<T>,)>
