Fix requirements permission documentation

Merged Jan Provaznik requested to merge docs-requirement-perms2 into master

What does this MR do?

Updates requirements permissions table, because:

  • guest can read requirements
  • reporter can create/edit requirements
  • only owner can destroy requirements but there is no way for users (either through UI or API) to delete requirements so this option is not mentioned
