Remove unnecessary inheritDocs from plugin

[Swiddis]

Is your feature request related to a problem?
The Kotlin KDoc Spec does not recognize the {@inheritDoc} annotation. Instead it automatically inherits documentation from one layer up. There are currently many methods throughout the Observability plugin that use this annotation and it produces broken documentation, simply removing it fixes the behavior.

What solution would you like?
Remove unused {@inheritDoc} from the codebase.

What alternatives have you considered?
N/A
