Fix InteractiveBrokers historical bar data bug

Pull Request

User "d2b" in Discord reported the following error:

Error on `_run_internal_msg_queue`: AttributeError("'coroutine' object has no attribute 'keywords'")

The issue originates from a bug in the historicalDataUpdate EWrapper override method of the InteractiveBrokersClientMarketDataMixin class. The root cause is the incorrect usage of a functools.partial object, which encapsulates the subscribe_historical_bars function. The functools.partial was being called rather than simply accessing the keywords attribute.

Looks like CI only failing due to a temporary GitHub runner glitch:

Error output:
No Python at '"C:\hostedtoolcache\windows\Python\3.11.7\x64\python.exe'

This normally clears after a few hours - I'll re-run the failing jobs later.
