Build docker container for aarch64 #1338
Description
It'd be nice if the getsentry/sentry-cli docker container were available for ARM/aarch64. I don't think any additional effort is required here except for specifying it as a platform when building the multi-arch container, be it through docker buildx/buildkit or manual manifest creation. I couldn't determine how exactly your releases to Docker Hub are made, and if there's just a script somewhere I could submit a PR to.
I've confirmed that docker build --platform=linux/arm64 --build-arg=BUILD_ARCH=aarch64 . in the repo root successfully builds a container with the CLI as expected.
