Breaking: #105686 - Avoid obsolete $charset in sanitizeFileName() 

Description 

The interface \TYPO3\CMS\Core\Resource\Driver\DriverInterface has been updated.

The method signature

public function sanitizeFileName(string $fileName, string $charset = ''): string

has been simplified to:

public function sanitizeFileName(string $fileName): string

Implementing classes no longer need to handle a second argument.

Impact 

This change has little to no impact, since the main API caller - the Core class ResourceStorage - never passed a second argument. The default implementation, LocalDriver , has therefore always behaved as if handling UTF-8 strings.

Affected installations 

TYPO3 installations with custom File Abstraction Layer (FAL) drivers implementing DriverInterface may be affected.

Migration 

Implementing classes should drop support for the second argument. Retaining it does not cause a conflict with the interface, but the TYPO3 Core will never call sanitizeFileName() with a second parameter.
