revert: chore(docs-app): load example files based on active deployment

This reverts commit d91a6bdbc66098ff7bbf8fa435ae5652fe6a795f.

The runnable examples cannot rely on the CDN for loading the common files,
because the CDN push does not happen at the same time as the docs are generated,
which means the doc examples are non-functional for an unforeseeable time.
