fix: Remove problematic type hints from extractor methods

Removed return type annotations (-> sd.ClassName) from all _get_*_reader
methods across all 9 extractors. These type hints were causing
AttributeError at import time because soccerdata module doesn't expose
these classes as direct module attributes.

Fixed extractors:
- fbref_extractor.py
- fotmob_extractor.py
- understat_extractor.py
- whoscored_extractor.py
- sofascore_extractor.py
- espn_extractor.py
- clubelo_extractor.py
- matchhistory_extractor.py
- sofifa_extractor.py

This resolves: AttributeError: module 'soccerdata' has no attribute 'FotMob'
