linux/arm64 image contains x86_64 binaries

[redbaron]

Looks like published image v1.20.1 for the linux/arm64 architecture was build as an x86_64.

$ docker run --rm -it --platform=linux/arm64 --entrypoint= ghcr.io/flant/shell-operator:v1.20.1
...

# file shell-operator
shell-operator: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), dynamically linked, interpreter /lib/ld-musl-x86_64.so.1, BuildID[sha1]=b432a223da3aa052bc17c3b2e244ed04d65d8f39, stripped

This happened since v1.19.5.
