Create/Edit Patron Blocks: Required fields are not using the right prop and cannot be read by screenreader

On the create/edit patron block page, these required fields: display description and block actions - should replace the current displayed asterisk with a red asterisk using the prop that supports the indication of a required field

• AND apply the right code so that these required fields are read by a screenreader

Definition of Done

• Verify that asterisk is red
• Verify required is read by a screenreader with NVDA screenreader

Scenario 1

• Given the the patron block create/edit page
• When a user gets to the Block actions section, change the header as follows
• Make it appear to be a section header (although it's not) by making it bold
• And change the asterisk to red
• And change the text as follows Block actions* (select all that apply)
• See attached mockup
• NOTE: when reviewing with pwanninger we realized the logic to require at least one field was already working, so retain that logic

Scenario 2

• Given the the patron block create/edit page
• When a user gets to the Block actions section
• And unselects any of the options
• Then remove the text Select any option (since that is now handled in the header)
• See attached mockup

MISC

• Change the following UI labels to sentence case:
  • Display description
  • Message to patron
