Docker container with platform linux/arm64 was build with GOARCH=amd64

[highercomve]

Tendermint version unreleased-master-023c21f3074189da5e8dfbe01ce8469dfdc90eb6 (tendermint/tendermint:latest container)

Environment:

• OS: Docker container for platform linux/arm64
• Install tools: docker pull --platform linux/arm64 tendermint/tendermint

What happened:
The docker container for linux/arm64 has the same amd64 binary as the linux/arm64 container.

Here more details about it:

docker run --platform linux/arm64 -it --rm -u 0 --entrypoint bash tendermint/tendermint:latest

What you expected to happen:
The binary on arch should be on arch architecture, like in this example:

docker run --platform linux/arm64 -it --rm -u 0 --entrypoint bash highercomve/tendermint:v0.35.4
bash-5.1# apk add file

Anything else we need to know:
I created a solution for this and use it in order to be able of running tendermint on a Raspberry PI 3, Raspberry PI 4 and an NVIDIA Tegra Nano
