cargo update
cargo test -p arrow-json --lib

Expected behavior
Tests should pass

Additional context

• @jayzhan211 observed this downstream in DataFusion: CI failed due to the dependency lexical-write-integer upgrade datafusion#13686
• @jonahgao fixed by pinning the lexical core version: Temporary fix for CI datafusion#13689
• Upstream ticket filed: [BUG] Regression lexical-write-float 1.0.4: jeaiii.rs:304:29: range end index 20 out of range for slice of length 19 Alexhuszagh/rust-lexical#191

I am pretty sure this is a regression in upstream lexical-core

I filed an upstream ticket (with reproducer): Alexhuszagh/rust-lexical#191

Alexhuszagh/rust-lexical#191 has been fixed upstream ❤️
