feat: add docker image for arm64

[raulb]

Description

Doing some benchmark tests I realized that conduit's image wasn't available for linux/arm64 (M4, etc...). (linux/arm64 is my current environment):

docker-compose -f containers/docker-compose.yml up -d

In the meantime

You can build for linux/arm64 locally by doing:

$ (conduitio/conduit) docker buildx build --platform linux/arm64 -t ghcr.io/conduitio/conduit:v0.13.1 --load .

Quick checks
