Subject: [PATCH] feat: add BTN_GRIPL/GRIPR/GRIPL2/GRIPR2 (Steam Deck back
 paddles)

These four button codes (0x224-0x227) are defined in the Linux kernel's
input-event-codes.h but were missing from this crate's scancodes.rs.

They are emitted by the hid-steam kernel driver for the Steam Deck's
back paddle buttons (L4/L5/R4/R5).
