Add support for linux/arm64/v8 Docker build

[gunpreet34]

Summary

When self-hosting the Fladder by pulling the latest image from the repo, the error shown is:

fladder The requested image's platform (linux/amd64) does not match the detected host platform (linux/arm64/v8) and no specific platform was requested

Could you please do a multi-platform build before pushing the image to the repo?

PS: I appreciate the work you've done, I just tested the android application a few hours ago and I'm impressed by the UI. I wanted to try the Fladder web but I'm facing some issues in building the docker image.

Error:

Basic Example

Right now, the solution is to clone the repo, build a local Docker image and then use that to spin up the container and that is fine but not scalable for everyone.

Drawbacks

I don't see any disadvantages of using multi-platform docker images (there are benefits though):

Good suggestion 👍🏼.
I've added them to the docker build step. The latest release v0.5.0 seems to have them build correctly. Let me know if they work as expected.
