 For hosts that make available the PHP fileinfo extension, uploaded files
 of mime type `application/json` are identified by that extension as
 `text/plain`.  Within the `wp_check_filetype_and_ext` function, it's noted
 that "a few common file types are occasionally detected as `text/plain`",
 but `application/json` is not listed as one of those common types.  For
 reference, the following types are listed:  csv, rtf, tsv, and vtt.

 I propose adding `application/json` to this list.  Otherwise, I believe it
 may be impossible to upload a JSON file on a host that uses this
 extension.
