Update to 4.23.0; fix test issues

[sbabcoc]

In this PR, I upgraded the Selenium version to 4.23.0.

In the process of testing this upgrade, I encountered test failures that led to the discovery of a few issues:

• The JSON converter that deserializes web service responses chained to its super-class when it encountered an Interaction object instead of returning the object as it should.
• I had failed to add clean-up code to close the browser session at the end of each test.
• The height value for elements changed from 72 to 54.
