chore: implement additional tsconfig properties

[justlevine]

What

This PR makes the following changes to tsconfig.base.json. Reasons are included alongside the change:

• noImplicitOverride: true - We're using classes, and we may want to extend them in future packages
• declaration: true - We're a library. d.ts files help end user IDEs
• sourceMap: true - We're a library, sourcemaps help end users debug
• isolatedModules: true - limits some ts edge cases.
• moduleDetection: "force" - Prevents unexpected behavior leaking from autodetection.
• resolveJsonModule: true - so we can import .json
• module|target: es2022 - the modern "stable" version.

Why

These are all noncontroversial, incremental improvements that don't require any existing code changes to satisfy.

Individual property explanations are here https://www.typescriptlang.org/tsconfig

Additional Info

Additionally set noUncheckedIndexedAccess and verbatimModuleSyntax to false, but they'll be handled in a separate PR since they require file changes.

• resolveJsonModule: true
• bumps module and target to ES2022
