Remove hardhat and replace with vitest (#27)

* Remove hardhat and related dependencies, replace with vitest

* Add vitest coverage report for 'yarn test'

* Fix incorrectly named test

* Resolve issues with vitest in packages/delegation-toolkit
- standardise vitest dependency across monorepo.
- update packages to 'type':'module' to fix vitest configuration resolution.
- fix exports in @metamask/delegation-core to correctly target commonjs and esm.

* Remove hardhat artifacts file
