Support ARMv6 (Raspberry Pi 1 Model B) for Docker Image Compatibility

Is your feature request related to a problem? Please describe.
I'm trying to run Nginx Proxy Manager (NPM) on a Raspberry Pi 1 Model B, which uses an ARMv6 architecture. Currently, there is no official support or image available for this architecture, making it impossible to use NPM on this device. The Pi 1 is still capable of running lightweight services and could be an ideal low-power reverse proxy for small self-hosted setups.

Describe the solution you'd like
I would like to request support for building and releasing a Docker image of Nginx Proxy Manager that is compatible with ARMv6, so that it can run on devices like the Raspberry Pi 1 Model B. This would allow a broader range of users to utilize older but still functional hardware.

Describe alternatives you've considered
I’ve tried running existing multi-arch Docker images, but they fail due to incompatibility with ARMv6.
Considered using other reverse proxy solutions but none offer the same simple UI and management features as NPM.

Additional context
Supporting this platform would greatly benefit hobbyists and those maintaining retro or ultra-low-power home lab environments.

The issue names no files, tests, or entry points. Start by locating the Docker image build and release configuration and checking how supported architectures are declared; done means a released image demonstrably runs on ARMv6/Raspberry Pi 1.
