response_headers_severity does not allow down value

[valugi]

This is about a website monitor attribute called response_headers_severity. The documentation states that the possible values are DOWN 0 - or Trouble 2. Setting this to 0 in terraform does not work - the value gets set back to 2.

  # module.spof_website.site24x7_website_monitor.website will be updated in-place
  ~ resource "site24x7_website_monitor" "website" {
        id                          = "396627000019683030"
      ~ response_headers_severity   = 2 -> 0

The same behavior happens in the web interface - Down value is not saved.
