build(deps): update indexmap requirement from ~2.11.4 to ~2.13.0

[dependabot]

Updates the requirements on indexmap to permit the latest version.

Changelog

Sourced from indexmap's changelog.

2.13.0 (2026-01-07)

• Implemented Clone for IntoKeys and IntoValues.
• Added map::Slice::split_at_checked and split_at_mut_checked.
• Added set::Slice::split_at_checked.

2.12.1 (2025-11-20)

• Simplified a lot of internals using hashbrown's new bucket API.

2.12.0 (2025-10-17)

• MSRV: Rust 1.82.0 or later is now required.
• Updated the hashbrown dependency to 0.16 alone.
• Error types now implement core::error::Error.
• Added pop_if methods to IndexMap and IndexSet, similar to the method for Vec added in Rust 1.86.

2.11.4 (2025-09-18)

• Updated the hashbrown dependency to a range allowing 0.15 or 0.16.

2.11.3 (2025-09-15)

• Make the minimum serde version only apply when "serde" is enabled.

2.11.2 (2025-09-15)

• Switched the "serde" feature to depend on serde_core, improving build parallelism in cases where other dependents have enabled "serde/derive".

2.11.1 (2025-09-08)

• Added a get_key_value_mut method to IndexMap.
• Removed the unnecessary Ord bound on insert_sorted_by methods.

2.11.0 (2025-08-22)

• Added insert_sorted_by and insert_sorted_by_key methods to IndexMap, IndexSet, and VacantEntry, like customizable versions of insert_sorted.
• Added is_sorted, is_sorted_by, and is_sorted_by_key methods to IndexMap and IndexSet, as well as their Slice counterparts.
• Added sort_by_key and sort_unstable_by_key methods to IndexMap and IndexSet, as well as parallel counterparts.
• Added replace_index methods to IndexMap, IndexSet, and VacantEntry to replace the key (or set value) at a given index.
• Added optional sval serialization support.

2.10.0 (2025-06-26)
