(attempt 2) Build: Add e2e-tests-dev task

[yannbf]

Closes #21546

What I did

We have been running e2e tests against built Storybooks, but not against Storybooks in dev mode.
This PR solves that!

How to test

Run a e2e-tests-dev for template, e.g. yarn task --task e2e-tests-dev --start-from auto --template react-vite/default-ts
