Description for a pipeline run is not compatible and cannot be disabled

jamesdumay added recently description display to blue ocean in JENKINS-41769. Unfortunately it is not rendering build description property in consistent manner. The build property is multi-line and supports HTML content, while its blue ocean presentation expects single-line and plain text.

I was already using this property, filling it with html tables, links and images, and now at blue ocean it presents itself as HTML source.

Possible solutions:

• allow to disable display of description in blue ocean
• make the blue ocean description rendered in same manner as it is in other parts of Jenkins
• make the blue ocean description relay on other property, i.e. Summary, Brief, Note
