add type checking

- fixes #1085
- include core, extensions, platform-bible-utils, platform-bible-react
- fix existing type checking errors
- add typecheck to pre-commit
- use `noImplicitReturns` instead of `consistent-return`
- type check in CI
- fix jsdom type check errors
- also make VS Code use the repo TS version
- remember to remove the patch and the type overrides when the BNF types are fixed
