CLI: Fix vite/jest issue with mocked global

[shilman]

Issue: #17516

What I did

• Support sb@next init --builder vite shorthand
• Support @storybook/builder-webpack5 in core.builder (vs just webpack5)
• Add a preview-head.html workaround for vite projects per Interactions-addon relies on polyfilled global (via jest-mock) #17516. Hope we can remove this soon.

How to test

yarn build cli
cd /path/to/vite-project
/path/to/storybook/lib/cli/bin/index.js init --builder vite
# or --builder @storybook/builder-vite
