Make showing file type, file size, or both optional

I've added some PHP Unit tests to cover this code change. I'm used to the old Drupal CI and I have to say the new GitLab instance is much, much better to work with. It even comes with all test running automagically setup with the include of a stock ".gitlab-ci.yml" file. There are warnings about linting errors on the MR, but the unit tests pass. At some point, an issue should be created to take care of the linting errors or change the linting configuration.

On the MR, I think I've done everything necessary and taken care of people already using the module with the update hook. I will try to test the update hook now locally on a Drupal site, but the code is ready to review.

I don't have a preference on what the description text is for the appending pattern form field so I'm open to suggestions on that. I think it is clear enough, but maybe there are Drupal conventions to use for describing tokens like that.

Based on feedback from a reviewer I am putting this back into needs work. There is at least an issue with menu links as you can see in the screenshot below.

...err welp, I thought the image upload would be different. The menu link text is HTML in a "" tag.

It would be good if we can add a test at a higher level that works with a Drupal instance, adds media, and then inserts the media for both content and field parsing.
