RulesVerifier should ensure that at least one of Recommendation or Description is filled in a Rule

[gfs]

Github's sarif upload feature requires the Text property of the Help property of each Rule to be populated. This field is a plaintext representation of the message shown to a user when an issue is found. Some rules have neither of these fields and thus result in an empty text property which fails to be uploaded to github, see #530.

The rulesverifier should require that at least one of the description or the recommendation is set, and the standard rules should all have descriptions/recommendations.

See microsoft/ApplicationInspector#544 for a PR to require the Description field. Recommendation is a DevSkim only field and would require additional work to implement in the DevSkim verifier, but as long as there is a Description field it should resolve the original issue in #530 more cleanly than the backup message.
