dockerSetupCommands doesn't work on Windows

[kichik]

Using dockerSetupCommands to with Windows runner image builders doesn't seem to work. I get:

Error while calling ssm:SendCommand: UnsupportedPlatformType

For example:

const windowsImageBuilder = FargateRunnerProvider.imageBuilder(stack, 'Windows Image Builder', {
  os: Os.WINDOWS,
  vpc,
  subnetSelection: { subnetType: ec2.SubnetType.PUBLIC },
  dockerSetupCommands: ['echo hello world'],
});
