fix type-check for test files (bun:test types + ES2020 BigInt support)

- Exclude __tests__ dirs from the main tsconfig (ES2017 target)
- Add tsconfig.test.json extending the main config with ES2020 target
and bun-types so BigInt literals and bun:test imports type-check cleanly
- Install @types /bun devDependency
- Update type-check script to also run tsc -p tsconfig.test.json --noEmit
