Updated component examples.

I felt these two articles lacked screenshots of the installed components so I provided them and revised the first section of each for readability.

I would prefere to have them autogenerates with cypress, so it gets' automatically updates on new joomla releases, maybe with some help from @muhme ?

I think I know how to do that. But there are 262 images in _assets folders. 182 of them are jpeg but mostly ought to be png. 80 are png. That is too big a problem for me!

It's a "vision" to have the images generated automatically, so if we can start somewhere it would be great

In my count figures I unintentionally included versioned docs. In the latest docs there are only 31 png files and 39 jpg files. Many of them are not Joomla screenshots and/or have annotations such as arrows or circles.

I ran into problems in my adventures with Playwright. It was fine for Help screenshots but tutorials required tailored Joomla installations that I did not have time to script (in many languages). I did do a few.

In this case could you set the "vision" aside and merge this PR?

of course
