Unify doc typing

Unify doc typing

### Description
<!-- Describe your changes in detail -->

Fixes #9168

This PR replaces common occurrences of [PEP 585](https://peps.python.org/pep-0585/) style type annotations with annotations compatible with older versions of Python.

I searched for instances of the following supported types from the PEP and replaced with their legacy typing couterparts.

* tuple # typing.Tuple
* list # typing.List
* dict # typing.Dict
* set # typing.Set
* frozenset # typing.FrozenSet
* type # typing.Type

```
grep -r "list\[.*\]" ./build --exclude-dir="./build/venv/*" --exclude-dir="./build/output/*" --exclude="changelog_[0-9]*\.rst"
```

I excluded changelog files from being altered, I think some of these could be changed if necessary but others are likely to require manual checking as the change may target the new typing style specifically.

For any examples that included imports, I tried to ensure that the correct typing imports were included and properly ordered.
