Add CreateEvent component stylings

[hnadrian]

• Reference Figma Design (https://www.figma.com/design/Z4ehMEyfixqSX5K5EJZ9ID/ccuss-project?node-id=65-150&t=dmg2wA6BtS6GP7GM-0)
  • You can also reference EventSignUp component if it is merged already.
• Make sure the spacing between fields, text colors, placements, etc. are consistent. Feel free to use your design brain if Figma needs some stuff added.
• You might need to make change in other components that was used like (AddVolunteerRoles)
