ICS email attachment files missing MIME type

Add MIME type for .ics files inside "wp-includes\class-phpmailer.php", function "_mime_types".

This should be pretty simple. Add the following to the function "_mime_types" (line 3533):

'ics'   => 'text/Calendar'

The main issue is that not all email clients can read these files correctly, since the .ics file are not assigned a correct mime type. For instance, gMail does not detect all events in the .ics file because of this and only detects the first one.

Hi there, welcome to WordPress Trac! Thanks for the report.

PHPMailer was updated to version 6.1.6 in [48033] / #41750.

The current version does include the MIME type for .ics, so I'm closing the ticket as fixed in WordPress 5.5.
