Summary0000103: ZStandard incorrect MIME type application/x-zstd
DescriptionIn the commit "PR/573: Nick Terrell: Add zstd support" was added a support for
for ZStandard compressed files with "application/x-zstd" MIME type.
But latter the official MIME type was assigned without the "x-" i.e. "application/zstd":
Steps To Reproduce$ touch test.txt
$ zstd test.txt
test.txt :1300.00% ( 0 => 13 bytes, test.txt.zst)
$ file -i test.txt.zst
test.txt.zst: application/x-zstd; charset=binary
Additional InformationAll GUI archievers (Ark, File Roller, Engrampa) internally using the correct "application/zstd" MIME type
