[docs] [issue32769] Add 'annotations' to the glossary

Guido van Rossum <guido@python.org> added the comment: (1) The word "stores" in this paragraph: A metadata value associated with a global variable, a class attribute or a function or method parameter or return value, that stores a type hint. (2) The description of how annotations are stored in __annotations__ in the following paragraph. (3) The omission of local variables from the lists of things in those paragraphs that can be annotated (those are the only category whose annotation is not stored at runtime). ---------- _______________________________________ Python tracker <report@bugs.python.org> <https://bugs.python.org/issue32769> _______________________________________
