Issue Resolved / Feature Added

Scrolling in VirtualList default story was very laggy

Resolution

Removed storybook/addon-docs from sampler app as it was not directly used. This dependency was causing extra rerenders on each component update.
Removing this dependency was causing an error on story load "Cannot read properties of null (reading 'useEffect')", caused by the fact that storybook and limestone or other enact dependencies might have different React versions. This was solved by forcing a single React version in webpack configuration

Additional Considerations

Updated React, react-dom and storybook dependencies to latest version

Testing in a packed version of Storybook brings better performance. In dev mode, there are still some lags.
