Fix banner alignment with actions

[adierkens]

Updates the styling of the banner component that includes a hidden-title and actions. Today, the presence of actions causes the icon and description to become misaligned (non-vertically centered), because the margins are updated to be slightly smaller when titles are hidden.

Pull Request Overview

This PR fixes a visual alignment issue in the Banner component where icons and descriptions become misaligned when the component has both hidden titles and actions. The fix ensures that styling adjustments for hidden titles are only applied when actions are not present.

• Updates CSS selectors to conditionally apply hidden-title styles only when actions are absent
• Adds a changeset file to document the patch release
