Doctool: Remove version attribute from XML header
We don't use that info for anything, and it generates unnecessary diffs
every time we bump the minor version (and CI failures if we forget to
sync some files from opt-in modules (mono, text_server_fb).

Holds an [Object]. If the object is [RefCounted], it doesn't update the reference count.

<description>
A weakref can hold a [RefCounted] without contributing to the reference counter. A weakref can be created from an [Object] using [method @GlobalScope.weakref]. If this object is not a reference, weakref still works, however, it does not have any effect on the object. Weakrefs are useful in cases where multiple classes have variables that refer to each other. Without weakrefs, using these classes could lead to memory leaks, since both references keep each other from being released. Making part of the variables a weakref can prevent this cyclic dependency, and allows the references to be released.
