[Fsss126]

Closes: #4042

Description

Setup proper type checking in stories and eliminated preexisting TS errors

What was done

• Fixed problem that importing .vue files in stories raised TS error "Cannot find module or its corresponding type declarations." via including *.stories.ts files in tsconfig.json Typescript erros in stories #4042
• Added separate tsconfig.build.json to pass to build:types so that stories still don't end up in generated type declarations
• Added typecheck script for type checking all project code including stories and hooked in precommit stage
• Fixed more TS errors that popped up on typecheck, namely:
  • Typed all stories with interactions play with StoryFn
  • Added "@testing-library/jest-dom" types to tsconfig to have jest-dom assertions methods on expect properly typed
