Follow-up of doctrine#11359

The table I suggested is probably not working, since the text for each method is too long. And what I really wanted is to make it more *scanable*. So I tried boldfacing - if this doesn't work, I'll try something else.

Questions:

1. This section here is basically the same as https://www.doctrine-project.org/projects/doctrine-orm/en/2.10/reference/dql-doctrine-query-language.html#hydration-modes ! So I'll try to merge them (in another PR), OK? I think the list is a better format (more scanable) - since those methods all work the same, there's no need for a full-blown code sample for each, IMO.

2. `getSingleColumnResult()` is missing.

See doctrine/collections#368 for the same
issue in doctrine/collections which has been fixed there.

The issue happens when using ->contains(). Running psalm emits

  > InvalidArgument - Argument 1 of Doctrine\ORM\PersistentCollection::contains
  > expects
  > TMaybeContained:fn-doctrine\common\collections\readablecollection::contains
  > as mixed, but … provided.

Solution: we should either not define @template TMaybeContained or
re-define the complete psalm docblock from ReadableCollection.

Repairing the docblock necessitates an update to the psalm baseline:
one "known issue" is no longer an issue and thus removed.

As announced in doctrine#11372 (comment), I merged the (mostly) identical sections.

* I changed the `const`s from `Query` to `AbstractQuery`
* I deleted this - mainly cause I didn't find a nice place for it:
    > In parentheses are the constants of the ``Query`` class which you can use with the
general-purpose method ``Query::execute(array $params = [], $hydrationMode = Query::HYDRATE_OBJECT)``.
