Is your feature request related to a problem? Please describe.
I want to create and maintain a platform independent docker-compose file to build my home automation system on any hardware, x86 VPS or Arm SBC.

Describe the solution you'd like
It would be useful therefore if Gotify were to use the Docker Multi-Arch build process so that it only be referenced by gotify/server regardless of which platform it is running on. (https://www.docker.com/blog/multi-arch-images/)

Describe alternatives you've considered
I could attempt to do the build process myself but it would then mean it would slowly drift out of sync with any updates and Watchtower would not work unless I went in and rebuilt the image myself when I knew there was an update.

Additional context
The Multi-Arch build process also builds more Arm versions than just v7 for example it also builds v6 and arm64 which would enable wider support of devices (older Pi's) or performance gains on more modern arm64 devices.
