gnome: Move cheese and epiphany to -apps
https://github.com/void-linux/void-packages/pull/20224

Description:
Other desktop environments like KDE or MATE don't add extra applications like `falkon` in the case of KDE or `mate-terminal` in the case of MATE. I think putting `epiphany` and `cheese` under the `-apps` package is a bit more coherent with the other DEs.
