fix: Add Github Actions and fix type errors(#18)

History of this squashed commit:
* Fix a test and type error

* Add github action tests

* Pass test in both node 18 and 20

* Remove some unused imports

* Add typecheck and build to CI

* Mute some type errors

* chore: fix type issues found after upgrading dependencies, see: cloudflare/workerd#1298

* Remove ts-nocheck

* Still disable threads for vitest to fix timeouts

* fix: simplify manifest upload by copying into a text

Locally in unit tests manifest upload could hang sometimes.

* Remove `threads: false` in vitest config

* Set pool to forks in vitest config

* Avoid pool option and avoid pining node types
