Update target to es2022

[gameroman]

Last time this was updated 2 years ago so it makes sense to do it now

Note

Low Risk
Low risk configuration change, but it can affect emitted typings/runtime expectations if consumers or tooling rely on ES2020-level libs or downlevel behavior.

Overview
Updates tsconfig.json to compile against ES2022 by bumping both compilerOptions.target and compilerOptions.lib from ES2020 to ES2022, enabling newer built-in APIs/type definitions during typechecking.
