[Documentation] UserGuide InstrumentAbstraction.md TSMSessionManager description

[yanli-dev]

Describe the bug
In UserGuide InstrumentAbstraction.md TSMSessionManager description could be confusing.

Querying Sessions
In a given test code module, you should create a new instance of TSMSessionManager at the beginning of your test method and pass it to the ISemiconductorModuleContext object as an input.

ISemiconductorModuleContext object is input to TSMSessionManager.

@yanli-dev, thank you for pointing this out. I believe the text should've read:

Please confirm this change would address your feedback, and we'll work it in as soon as possible.
