[DOC] Add type hints for shapelet-based collection transformation.

[baraline]

Describe the issue

Other modules are increasingly using type hints in the function declaration, the shapelet-based tranformation module should do the same.

Suggest a potential alternative/fix

Add type hints to algorithms in aeon/transformations/collection/shapelet_based. One PR can be opened for each algorithm if preferred, as some are quite large.

I don't remember if we have a bot for this, but you can do it manually on the Assignees tab on the right side, I'll do it for you this time. Happy coding, and thanks for contributing !

There was an error in the docs that we have now fixed, but have to wait for a release for it to appear on the stable branch. Have to start with @aeon-actions-bot

I think you need write access to manually assign yourself

[Datadote]

Yep, I don't have access to manually assign myself (Tried on other issues).

I started a draft pull request with type hints, and some styling questions in #1926 . Thank you for the help
