Message:

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.
