wrong mimetime for gzip files

[liedekef]

In the file wp-includes/functions.php, function wp_get_mime_types(), the mimetype for gz|gzip is indicated as "application/x-gzip", while fileinfo (and /etc/mimetypes) return "application/gzip".

Also, it seems this line is missing tgz, so I would suggest changing this from:

'gz|gzip'                      => 'application/x-gzip',

to:

'gz|gzip|tgz'                      => 'application/gzip',

Hey guys, patch looks good, thanks.

I have just updated it to tweak unit test with the new value.

Mentioned in the recent Media Component meeting, this looks like a good ticket for 5.8. Adding to the milestone for visibility.

Thanks to @liedekef for reporting this. We recently reviewed this during a recent [bug-scrub session]​https://wordpress.slack.com/archives/C02RQBWTW/p1623097314362900. With Beta 1 coming up in a day this could be a good one for future releases. Milestone updated. Thanks
