feat: load TypeScript config from tsconfig package instead of ts-jest (#471)
* chore(deps): add `tsconfig` package on @vue/vue2-jest * feat: add `getTypeScriptConfig` util function * feat: use `getTypeScriptConfig` on typescript transformer * feat: remove `getTsJestConfig` function * chore(deps): remove ts-jest dependencies * chore(deps-dev): remove ts-jest from e2e projects * feat: remove info log * feat: support `createTransformer()` on customTransformer
