Add more metadata information

[p2004a]

I will keep updating this top comment with list of metadata to add:

• More gametypes, 1v1,2v2,3v3... Maybe stuff in https://docs.google.com/spreadsheets/d/1rn4kIIc9Nnyv_ZiBxXvNXdhUSnh15aLrLsQXmtUBJt8/edit#gid=0 is good and can be used as a seed?
• Add more photos:
  • Header Image
  • SEO Image
  • Image Gallery (multiple upload)
  • 3d/perspective image
• Startbox configuration
• Pretty display name
• Explicit version (also maybe try to automatically extract?)

Note: Some of this information for subset of maps can be pulled from Airtable: https://airtable.com/appUamRzPAXhVUuI1

All the current website and other consumers needs are currently covered, so marking this as resolved.
