Add Comment Explaining noqa in the test___main__() Test

[mcdonnnj]

🚀 Feature Proposal

A recently added test relies on a # noqa line to avoid an F401 | module imported but unused warning as seen here:

skeleton-python-library/tests/test_example.py

Line 52 in 0db80d1

import example.__main__ # noqa: F401

There should be a brief comment explaining why this is being done for future codebase delvers.

Motivation

Properly documenting rationale for intentionally disabling warnings/errors is good.

An explanation was added in #56 and is merged:

skeleton-python-library/tests/test_example.py

Lines 51 to 57 in 0f6efe0

	# F401 is a "Module imported but unused" warning. This import
	# emulates how this project would be run as a module. The only thing
	# being done by __main__ is importing the main entrypoint of the
	# package and running it, so there is nothing to use from this
	# import. As a result, we can safely ignore this warning.
	# cisagov Libraries
	import example.__main__ # noqa: F401
