Subject: [PATCH] [6.x] Fix validating image/jpeg images after Symfony/Mime
 update (#35419)

* [6.x]  Fix validating image/jpeg images after Symfony/Mime update

Symfony/Mime v5.20 changed the returned extension for an image with image/jpeg mime type: symfony/mime@aa1d922. This commit adds `.jpg`, which fixes the validation.

* [6.x] Add test for image validation with jpg extension
