Brings language/types/callable.xml up to date with the upstream rewrite (EN-Revision 312c0c7b39d0722c419f6784cbda24823220dfb3): - Title "Callbacks / Callables" → "Callables". - New intro paragraph with a short informalexample showing callable as a parameter type. - Section "Übergabe" renamed to "Erstellung von Callables" and reorganized around how callables are created. - New itemizedlist enumerating the four ways to create a callable (Closure object, string, array with class+method, object implementing __invoke). - New explanation of how Closure objects can be built (anonymous function, arrow function, first-class callable syntax, Closure::fromCallable) with a runnable example showing all four. - New note about scope binding (Closure is bound to creation scope, callables as string/array are resolved in the call scope). - New paragraph and note about context-dependent callables (parent::method, ["static", "method"]) deprecated since PHP 8.2.0. - Existing call_user_func example expanded with a new Type 5 case using MyClass::class and renumbered subsequent types; output is now shown via a <screen> block. - Standalone Closure example removed (content merged into the new Closure example earlier in the section). - Dropped the obsolete <!-- $Revision$ --> SVN marker. Sie-Form beibehalten, bestehender Maintainer (simp) bleibt.
