feat(ci): Remove webpack job from acceptance workflow (#35858)

The webpack job creates the frontend dist and the acceptance jobs hold their execution for the job to finish.
Unfortunately, sometimes, the frontend dist fails to download even though the artifact is available.

I don't know the reason (it could be a matter of timing) but I would rather have a more stable execution.

You can see an example of the documented issue in here:
