crate actually requires indexmap >= 2.3.0

[lucasfernog]

the toml crate uses the iter_mut2 method on IndexMap, which was introduced on indexmap 2.3.0 but the crate does not enforce that in the Cargo manifest file

Interesting, we had it right for toml_edit but not toml. I must have not copy/pasted nor used cargo add. Because it was right in toml_edit our minimal-versions CI job missed this. Using workspace.dependencies would help but that is broken in several ways (default-features = false, making it harder to notice when public deps are bumped by a major version etc).

#998 fixes this.
