Move the Stories view displays to Varbase News Base and Varbase Events Base

Problem/Motivation

Making the home page Stories section dynamic in #3616545 added two Views block displays to this recipe's recipe.yml: a featured display for views.view.news and a latest display for views.view.events, about three hundred and eighty lines in total.

Neither belongs here. This is a site template; the news view is owned by Varbase News Base and the events view is reshaped by Varbase Events Base. Defining the displays in the site template means no other consumer of those recipes can use them, and the recipe carries several hundred lines of view configuration it should never have owned. The exported displays also carried vartheme_bs5_educare: component ids, which only work on this template's theme.

Proposed resolution

Move both displays to the recipes that own their views, and remove them from here:

• views.view.news featured → Varbase News Base (#3616585);
• views.view.events latest → Varbase Events Base (#3616587).

Both ship with the base theme's component ids, and this recipe's existing setViewsComponentStyleTheme actions repoint them to vartheme_bs5_educare at install, exactly as they already do for every other display. The Home page keeps the two Views blocks it places; only the display definitions move.

This issue depends on both of the above being merged and released first.

Release notes snippet
