Change `x-content-type-options` rule so that it limits the usage of the `X-Content-Type-Options` header to scripts and stylesheets as modern browsers actually only respect the header for those types of resources¹. Also, sending the header for resources such as images, creates problems² in some older browsers. - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - ¹ https://fetch.spec.whatwg.org/#x-content-type-options-header ² whatwg/fetch#395 Fix #767
