Enable rendering related capabilities for unit tests with Vitest UI

[cnotv]

Description

Vitest UI provides a dashboard for running and visualizing tests using browser mode.

Context

In several occasion (e.g. #8999 and #10000) it's required to test DOM/rendered elements for unit tests, which is currently not feasible with Jest nor Jest-dom.

Note: This is part of the effort to extend tests capabilities:

• Setup and introduce visual regression tests #9057
• Define performances tests #9845

Required to test #9668

[cnotv]

After extensive research of all the possible existing libraries and configurations, it was found that it is more convenient to simply generate screenshots for visual testing.
I'm bouncing back to #9057 unless a better configuration is found.
