Update path for volto-light-theme in styleguide (#96)

* Update path for volto-light-theme in styleguide

because volto light theme is now a monorepo it has a different folder structure then before. That's why I made these changes to go into volto-light-theme/frontend/packages/volto-light-theme/src instead of volto-light-theme/src

* Added Changelog entry

* updated the instructions to install VLT in the styleguide
