Add docker support for linux/arm64/v8

[kitti-katy]

I have Mac M1 and when trying to run the docker image from docker.io/parity/substrate-api-sidecar:latest I get:

➜  substrate-api docker run --rm -it --read-only -p 8080:8080 parity/substrate-api-sidecar
WARNING: The requested image's platform (linux/amd64) does not match the detected host platform (linux/arm64/v8) and no specific platform was requested

#
# Fatal process OOM in Failed to reserve virtual memory for CodeRange
#

qemu: uncaught target signal 5 (Trace/breakpoint trap) - core dumped

Hmm, this is interesting. I am running it on Macbook Pro M2 and have no issues. I'll give this a look.

Okay so I was able to reproduce the warning: That being said the image still runs which is also weird.

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

Currently also getting the following error when running docker build --platform linux/arm/v8 -t substrate-api-sidecar . or just plain docker build -t substrate-api-sidecar .:
