ci(v2): test swizzle on CI using v2 website

[Simek]

Motivation

#3830 - as reported, there is an issue with swizzled component form theme-classic right now.

To prevent new swizzling errors from slipping into the release I have decided to add the swizzle test of most of theme-classic, theme-search-algolia and theme-live-codeblock components to the CI pipeline. Test is based on the Docusuaurs V2 website and helper scripts starting with swizzle:v2 have been added to the main package.json.

The list of components is subjective, feel free to change or update it 🙂

Currently the test step will fail for:

• DocPage and DocSidebar components due to the same error as reported in the mentioned issue

  ModuleNotFoundError: Module not found: Error: Can't resolve '../icons/arrow.svg'

After fixing those problem the step run should be successful.

Thanks, that's a good test idea 👍

We should probably ensure the test pass before merging 😅

FYI: From the day when #3854 has been merged (Dec 01, 2020), running all the commands locally, in same order as in workflow results in successful build. The server compilation seems to fail only on the CI. I have tried many ideas to fix this, all of them failed.

To be honest, I don't want to waste any minute more on this problem, @slorber can you step in?
