Add missing dependency filetype for python 3.13+ (infra)

[Hook25]

Description

Filetype was added to replace the deprecated imghdr, but it wasn't included in any of the dependencies anywhere. This fixes it.

Note: I didn't add it to the core24 snap as that uses python3.12, will have to remember to add it to the core26 one.
