Update indexmap requirement from 1 to 2

[dependabot]

Updates the requirements on indexmap to permit the latest version.

Changelog

Sourced from indexmap's changelog.

• 2.0.0

  • MSRV: Rust 1.64.0 or later is now required.

  • The "std" feature is no longer auto-detected. It is included in the default feature set, or else can be enabled like any other Cargo feature.

  • The "serde-1" feature has been removed, leaving just the optional "serde" dependency to be enabled like a feature itself.

  • IndexMap::get_index_mut now returns Option<(&K, &mut V)>, changing the key part from &mut K to &K. There is also a new alternative MutableKeys::get_index_mut2 to access the former behavior.

  • The new map::Slice<K, V> and set::Slice<T> offer a linear view of maps and sets, behaving a lot like normal [(K, V)] and [T] slices. Notably, comparison traits like Eq only consider items in order, rather than hash lookups, and slices even implement Hash.

  • IndexMap and IndexSet now have sort_by_cached_key and par_sort_by_cached_key methods which perform stable sorts in place using a key extraction function.

  • IndexMap and IndexSet now have reserve_exact, try_reserve, and try_reserve_exact methods that correspond to the same methods on Vec. However, exactness only applies to the direct capacity for items, while the raw hash table still follows its own rules for capacity and load factor.

  • The Equivalent trait is now re-exported from the equivalent crate, intended as a common base to allow types to work with multiple map types.

  • The hashbrown dependency has been updated to version 0.14.

  • The serde_seq module has been moved from the crate root to below the map module.

• 1.9.3

  • Bump the rustc-rayon dependency, for compiler use only.

• 1.9.2

  • IndexMap and IndexSet both implement arbitrary::Arbitrary<'_> and quickcheck::Arbitrary if those optional dependency features are enabled.

• 1.9.1

  • The MSRV now allows Rust 1.56.0 as well. However, currently hashbrown 0.12.1 requires 1.56.1, so users on 1.56.0 should downgrade that to 0.12.0 until there is a later published version relaxing its requirement.

Build failed:

Again, it seems to be the iOS build failing to find a new version of a crate:

 [2023-06-26T07:37:47Z ERROR cargo_dinghy] failed to select a version for the requirement `hashbrown = "^0.14"`
    candidate versions found which didn't match: 0.13.2, 0.13.1, 0.12.3, ...
    location searched: crates.io index
    required by package `indexmap v2.0.0`
        ... which satisfies dependency `indexmap = "^2"` of package `gdnative-core v0.11.3 (/Users/runner/work/gdnative/gdnative/gdnative-core)`
        ... which satisfies path dependency `gdnative-core` of package `gdnative v0.11.3 (/Users/runner/work/gdnative/gdnative/gdnative)`

This seems to be a pattern seen with other recent dependabot PRs that failed, e.g. #1050

There do not seem to be any relevant issues in the cargo_dinghy repo, which does still seem to be maintained. We are using an older version 0.4.71 as opposed to the latest 0.6.4 though, which may or may not be relevant. Perhaps we should try bumping that first.

I'm not sure if it's the version bump or the delay, but the CI seems to pass now, so I'll merge this.
