Closing this ticket as there is no bug. The issue with me not reading the documentation correctly. The correct syntax is:

additional_iso_files {
  cd_files = ["vendor-data"]
  cd_content = { "/almalinux-9-x86_64.ks" = templatefile("${abspath(path.cwd)}/templates/almalinux-9-x86_64-ks.pkrtpl.hcl", local.kickstart_template_vars) }
  cd_label = "cidata"
 }
