Chore: Update Dependencies, Linting, and TypeScript

[bachmacintosh]

Description

This PR is a one-shot at updating all of the devDependencies, switching the package manager to PNPM, updating ESLint/typescript-eslint and using a shared config, and updating the TypeScript development version alongside widening the supported TypeScript versions.

Any changes to code are merely side-effects from updated linting rules. No logic will change as part of this PR. That said, it will mean a patch version will go out just in case.
