[5.x] Bump symfony/filesystem

[nitinl-cogapp]

Hi,

While upgrading some other libraries I notice Craft has pinned symfony/filesystem:^6.3.

Looking at the symfony/filesystem changelog I can't see any breaking changes, would you be able to bump this to support v7/8?

Thanks for the suggestion! Craft 5.11.1 is out with support for symfony/filesystem 7.x and 8.x. (#19540)
