chore: upgrade to TypeScript 5.7, ensure tsconfig targed and lib properties match the APIs we support (#9473)

TS 5.7 added support for ES2024. By keeping target: “esnext”, we would
have accidentally set our minimum supported ES version to ES2024.

This sets it to ES2022, which is the version supported by Node 18
