YSP-670: Spotlights provide H2 in Banner Section

Description of work

• Adds Heading level to portrait and landscape spotlights now that they are in the banner options
• Wiring done also in Atomic and Component Library Twig -- please review these as well

Functional testing steps:

• Create a spotlight in the banner
• Set the title to be either visibly hidden or hidden
• Modify your spotlight to use a heading level of H1
• Verify it renders correctly with an H1
• Verify that the first spotlight's top-margin is set to 2rem
• Verify that other spotlights added that aren't at the top are not set to 2rem
• Ensure that other banner blocks placed at the top do not exhibit this spacing
• Ensure that spotlights added to a banner whose first block was not a spotlight spaces as expected
