Title: [forms] Remove tip for skipping validation group section

I think this section has no additional value for the user as this statement could be added on top of every section: If you do not need any feature you may skip the docs for it ;-)

The important link to the validation groups section is not lost because it is available in the next paragraph after the removed tip.
