[alexander-schranz]

Currently there are many core cache warmers missing in the documentation:

@alexander-schranz thanks for this contribution. Sadly, solving this is more complicated than it looks in modern Symfony versions. Since apps are now much more modular, the list of warmers depends on the components/bundles you pick. For example, my list of warmers for the Symfony Demo app is different that the list you showed here:

$ php bin/console debug:container --tag=kernel.cache_warmer

So, to avoid confusion and to make docs easier to maintain, I've merged your PR but, after that, I've replaced in 8953c9d the table of cache warmers with the debug:container command.

Thanks for understanding!

@javiereguiluz sounds reasonable did stumble over this because of a symfony certification question in the university where TemplateCacheWarmer was an answer possibility but not listed in the docs and was not checked by me. So I was confused why my answer wasn't correct 🙈
