[FR] Arm64 docker image

[joshwd36]

I wasn't sure whether to put this as a bug report or feature request.

Is your feature request related to a problem? Please describe.
I'm a big fan of pinchflat and use it on a raspberry pi. Unfortunately the latest docker image doesn't have arm64 support so I'm still using the previous version.

Describe the solution you'd like
Generation of an arm64 docker image

Describe alternatives you've considered
The old version still mostly works, but I know that yt-dlp has to be kept fairly up to date to keep working.

Additional context
If there is something I've missed and it's possible to use the latest image on arm devices Iet me know, I'm not a docker expert
