[Dataset quality] removing empty prompt (#192089)

The empty prompt as of now is just informative

After introducing other dataStream types within the page, the empty
prompt became a hindrance in the UX preventing users to properly select
a dataStream type when they have no data related to that type in the
environment.

This PR is about removing the empty prompt in favour of an empty state.
We want to keep the prompt only in case we have a place where to
redirect users to add relevant data
