Storybook build fails, blocks deployment of Documentation

[stevepiercy]

@sneridagh @davisagli for Documentation, we don't build any Storybooks for PR previews (it would be redundant to those done here in Volto), but we do build and deploy the Volto Storybook to https://6.docs.plone.org/storybook/. See:

• documentation/Makefile

  Lines 225 to 227 in 77eb1d3

  	.PHONY: storybook
  	storybook:
  	cd submodules/volto && pnpm i && pnpm build:registry && pnpm --filter @plone/volto build-storybook -o ../../../../_build/html/storybook

• documentation/.github/workflows/build_deploy.yml

  Lines 38 to 64 in 77eb1d3

  	restore-keys: |
  	${{ runner.os }}-pnpm-store-
  	- name: StoryBook build
  	run: make storybook

We need to update these files as well, per this failure to deploy documentation.

Can either of you make a recommendation or PR?
