Build docker images for other architectures

[josecelano]

If you look at the Dockerfile:

RUN cargo chef cook --release --target x86_64-unknown-linux-musl --recipe-path recipe.json
...
RUN cargo build --release --target x86_64-unknown-linux-musl --bin torrust-tracker

We are only building for the x86_64-unknown-linux-musl architecture.

We could build docker images for different architectures.

The Containerfile has changed but this is something we still have to add.
