OPTION_UPLOADED_FILE_NAME_PATTERN does not write specified path on disk

[Geolim4]

Describe the bug
When you create an imageField field with a custom pattern:

        yield ImageField::new('documentFile')
            ->setColumns(4)
            ->setBasePath('api/v1/document/download')
            ->setUploadDir("uploads/documents/")
            ->setUploadedFileNamePattern('/[year]/[month]/[day]/[slug].[extension]')
        ;

The stored string in entity is good:
/2024/08/16/xxxxxxxxx.jpg

But the path written on disk is incorrect as it is
uploads/documents/xxxxxxxxx.jpg
instead of
uploads/documents/2024/08/16/xxxxxxxxx.jpg

To Reproduce

        yield ImageField::new('documentFile')
            ->setUploadDir("uploads/documents/")
            ->setUploadedFileNamePattern('/[year]/[month]/[day]/[slug].[extension]')
        ;
