This is a proposal to show only DS projects on the newly introduced landing page (at least by default?).

On the newly introduced landing page, there seem to be shown all projects relevant to the logged in user despite they are DS projects or not. I think that RHOAI landing page should show information only about the RHOAI resources that are most relevant to the user. As such, I think that only true DS projects should be listed there - at least by default, if we intend to make this configurable.

Another reason to backup this statement is a fact that this is how we do it on the Data Science Projects page already - only DS projects shown by default; all projects shown only once user chooses appropriate option via a select box.

See attached screenshots for more info.
