Description

This change provides details on the expected value for kOrtEpDevice_EpMetadataKey_OSDriverVersion and provides an example in the plugin EP tests.

Motivation and Context

We introduced a new EP metadata key called kOrtEpDevice_EpMetadataKey_OSDriverVersion in #26616 but neglected to provide sufficient detail to guide EP authors in how to fill in the value for this key. This PR is an attempt to address that gap.
