refactor(GlAlert): isolate limited width styles
- Integration branch: gitlab!63792 (merged)
What does this MR do?
This moves alerts' max-width CSS rules to a dedicated selector. While this doesn't change anything as to how the component looks, it will give us more flexibility when dealing with HAML alerts in GitLab: we can combine gl-alert-max-content
styles with some of GitLab's own styles to align alerts content width with Gitlab's primary content width.
