Added ShadPS4 Flatpak

[Aeonitis]

Addressing issue #1309, this PR is a draft I created in my best ability to help push the ShadPS4 Flatpak for inclusion in the Emudeck.

Please feel free to criticize this PR as I am new to this project. I have the flatpak install function as a TODO in the comments.

To be confirmed

• I believe ShadPS4 uses a Playstation profile in terms of save data:

not SRM as of now...

EmuDeck/README.md

Line 20 in 84aee7c

- Every Emulator needs to have a SRM profile and follow the AmberElec hotkey mapping.

• Also need to decide/determine if the emulator's native config file config.toml which ShadPS4 generates should be separated from another ShadPS4 config file tailored for emudeck setup (Maybe named ShadPS4_Emudeck_config.yml)
