Add documentation about Typed Dictionaries

[ActualDio]

Godot 4.4.1

There's nothing I could find in the docs explaining how to make a typed dictionary and I had to guess it was Dictionary[key_type, value_type]

Places where it should be added:
https://docs.godotengine.org/en/4.4/tutorials/scripting/gdscript/static_typing.html
https://docs.godotengine.org/en/4.4/tutorials/scripting/gdscript/gdscript_basics.html#doc-gdscript-builtin-types
https://docs.godotengine.org/en/4.4/classes/class_dictionary.html#class-dictionary

This already exists for the static typing page, see here, here for GDScript basics, it is however missing from the documentation for Dictionary

Make sure to check the documentation in latest to make sure you're not seeing an outdated version

The changes were made in:

• Document typed dictionaries in GDScript #10747

And are waiting for cherry-picking for 4.4
