Upload: Add a check in `wp_check_filetype_and_ext()` to account for CSV files having the `application/csv` MIME type. 

Previously, the PHP Fileinfo extension used to detect CSV files as `text/plain`.

In PHP 8, this has changed, and CSV files are detected as `application/csv`.

Follow-up to [44438].

See #50913.
