Describe the bug

Hi,

I am trying to install helm/chart from the AWS ECR, but ran into error when the kubectl_handler pulls the helm/chart. Looks like it is reading the entire ecr login and helm pull commands as a file name. Please see error below (I masked our aws account id and the repo name):

[ERROR] FileNotFoundError: [Errno 2] No such file or directory: 'aws ecr get-login-password --region us-east-1 | helm registry login --username AWS --password-stdin xxx.dkr.ecr.us-east-1.amazonaws.com; helm pull oci://xxx.dkr.ecr.us-east-1.amazonaws.com/xxx --version 0.1.0 --untar': 'aws ecr get-login-password --region us-east-1 | helm registry login --username AWS --password-stdin xxx.dkr.ecr.us-east-1.amazonaws.com; helm pull oci://xxx.dkr.ecr.us-east-1.amazonaws.com/xxx --version 0.1.0 --untar'
Traceback (most recent call last):
  File "/var/task/index.py", line 17, in handler
    return helm_handler(event, context)
  File "/var/task/helm/init.py", line 85, in helm_handler

  File "/var/task/helm/init.py", line 126, in get_chart_from_oci
    output = subprocess.check_output(cmnd, stderr=subprocess.STDOUT, cwd=tmpdir, env=env)

    restore_signals, start_new_session)
  File "/var/lang/lib/python3.7/subprocess.py", line 1551, in _execute_child
    raise child_exception_type(errno_num, err_msg, err_filename)

Expected Behavior

helm/chart pull and installation should work when chart is stored in AWS ECR.

Current Behavior

kubectl_handler throws FileNotFoundError.

Reproduction Steps

Add a helm/chart as below in code:

new eks.HelmChart(scope, 'xxx', {
cluster: cluster,
chart: 'xxx',
release: 'xxx',
repository: oci://${accountId}.dkr.ecr.${region}.amazonaws.com/xxx,
namespace: 'kube-system',
version: '0.1.0'
});
