Add styling option to more closely match Dynamic Forms

[JodieM]

Describe the solution you'd like
For adding an Indicator Bundle to a Dynamic Forms page, I would like the styling to more closely match the styling of Dynamic Forms.
This will be especially useful for adding Indicator Bundles between field sections.

Describe alternatives you've considered
Adding just a regular looking bundle to a Dynamic forms page. It all performs well, but it can just look a little better.
