Would be best if this defaults to null or an empty string if the input is not found, rather than always linux/amd64.
Then elsewhere in the code, include conditions like (pseudocode):

if platform != null {
  podmanArgs.push("--platform ${platform}")
}

const additionalArgs: string = core.getInput('additional-args')
const chown: string = core.getInput('chown')
const rootfs: string = core.getInput('rootfs')
