Accented characters in filenames are not properly normalized since the 4.0.8 update

I submitted a first MR. Can't figured out how to make tests works (very first assertion of the module test Class failed, derivatives are not in the "file--file" json:api response, I don't know why). So I didn't wrote a test for now, sorry.

Thank you very much, it worked for me.

When will this be included in a new release ?
I have added it as a patch for the moment.

This solves the issue I'm having with JSONAPI's following error:

The website encountered an unexpected error. Please try again later.
AssertionError: A JSON:API response failed validation (see the logs for details). Please report this in the issue queue on drupal.org in assert() (line 117 of core/modules/jsonapi/src/EventSubscriber/ResourceResponseValidator.php).

I'm submitting a patch for now until this issue gets merged.
