fix #20828

I did not listed the AsTwigTest attribute in the attributes list as no doc make mention of use case of this attribute. Do I had it anyway without any link to it (or a link to the twig documentation)?

Also I hope my wording is correct, feel free to ask me any adjustment 😄

I followed the plan of @javiereguiluz

I have no clue why the CI fails to build the docs, I can build it properly on my end 😞

I've added a few comments. I find it hard to juggle the old and new ways of doing things in the same doc without making it too complex to understand; but it looks fine to me the way it is.

Thanks for the comment GromNan, it's very appreciated especially since I'm still new to the doc repository. I'm slowly starting to get the hang of how to write it 🎉. I'll apply your suggestions tomorrow 😄

We avoid subjective words like "simple". "Plain" or nothing would be more adapted.

When using attributes to extend Twig, the services are initialized only when
the functions or filters are used to render the template. But in case you use the
classic approach by extending the ``AbstractExtension`` class, Twig initialize all extensions before
rendering rendering any template, even if the template doesn't use an
extension.
