Describe the Bug

Setup

Adobe Illustrator files come with 1 of 2 mimeType's, where pdf one is the recent one.
application/vsn.adobe.illustrator, application/pdf

Error

Configuring an upload collection allowing both, still doesn't let me upload an Illustrator .ai file.

We receive a
ValidationError: The following field is invalid: mimeType

Out of some reason the file is interpreted as a 'application/postscript' even though getting File infos tells us its a pdf

file --mime-type -b my_illustrator_file.ai 
application/pdf

To Reproduce

Configure a upload collection with

upload: {
   mimeTypes: [
     'application/vsn.adobe.illustrator',
     'application/pdf',
   ],
 },

Try to upload an illustrator file.

[patricsgamma]

With the knowledge that 'application/postscript' works we can get around the issue.
But its still strange and misleading when the OS tells you a file is a certain mimeType and then it turns to something different on upload into the CMS.
