refactor: :recycle: update deprecated usage to use `typing.deprecated`

[Paillat-dev]

Summary

Fixes #1917 Redo of #2655

The previous version of the PR did not work correctly with type checkers, this one does, with the compromise of needing to use the @deprecated(deprecated_message(...)) syntax. This allows for type checkers to mark methods as deprecated and do some kind of strike trough like shown below:

I need some input, specifically we should probably ditch the strict formatting for deprecation messages entirely to stay in confomrity with python syle guides so idk pls give opinions
