device-pine64-pinephone: update UCM config for new headphone jack name
The previous name stopped being valid with the kernel 6.8 upgrade. This caused ALSA to think a headset was connected, which in turn caused callaudiod to select the Headphones port in the PA sink instead of Earpiece / Speaker.
I missed this in my own kernel upgrade testing because I use a custom callaudiod that doesn't care about the headphones port. I now confirmed the issue with regular callaudiod and that this change fixes it.
Fix provided by @airtower-luna in the pmOS Matrix room.
