Bug 1706465 [wpt PR 28606] - Add JSON modules tests for charset, inte…

…grity, and MIME type parameters, a=testonly Automatic update from web-platform-tests Add JSON modules tests for charset, integrity, and MIME type parameters Add JSON modules tests for the following: - The <script> element's integrity attribute is respected. - JSON modules are always decoded as UTF-8 regardless of Content-Type or the document's encoding. The existing coverage we had on this in utf8.tenative.html was renamed to charset.html, refactored, and expanded. - Adding parameters to the MIME type doesn't prevent it from being evaluated as a JSON MIME type. Note, some of the existing MIME type tests for */*+json still fail because it seems the spec issue on these at whatwg/mimesniff#112 hasn't been fully resolved. I'll follow up with that separately.
