[tests] Revive Forget e2e tests

--- 

Revives e2e test infra from #587. 

- All React component-like functions are compiled. 

- `yarn jest` runs each e2e test twice (forget and no forget) 

Github Actions is already running `yarn test`, which includes all jest tests 

``` 

Run yarn test 

yarn run v1.22.19 

$ yarn workspaces run test 

> babel-plugin-react-forget 

$ yarn jest && yarn snap:build && yarn snap 

$ tsc && jest 

PASS main src/__tests__/Result-test.ts 

PASS main src/__tests__/DisjointSet-test.ts 

PASS e2e with forget src/__tests__/e2e/hello.e2e.js 

PASS e2e no forget src/__tests__/e2e/hello.e2e.js
