Description

Reproduce:
1) Upload a file named "Placeholder.pdf" in the Filelist module
2) Rename the file to "..Placeholder.pdf"

In TYPO3 v12 the file will disapear in the file list without an error.
The file still exists on the filesystem.

In TYPO3 v10 following error is thrown:

File ..Placeholder.pdf is not valid (".." and "//" is not allowed in path). in typo3/sysext/core/Classes/Resource/Driver/AbstractHierarchicalFilesystemDriver.php line 53

Expected:
Uploading or renaming a file to a name starting with two dots is possible.
