igc binary download issues with Apple M1 Silicon

I am testing with Multipass VM using an Apple M1 based Mac.

When applying the [105 layer to install OpenShift on IBM Cloud](https://github.com/IBM/automation-ibmcloud-infra-openshift/tree/main/1-quickstart/105-ibm-vpc-openshift), I encounter the following error:

╷
│ Error: External Program Execution Failed
│
│ with module.ibm-activity-tracker.module.clis.data.external.setup-binaries,
│ on .terraform/modules/ibm-activity-tracker.clis/main.tf line 22, in data "external" "setup-binaries":

│ Error Message: Error downloading igc from https://github.com/cloud-native-toolkit/ibm-garage-cloud-cli/releases/download/v1.37.6/igc-linux
│

When applying the [200 layer to install GitOps](https://github.com/IBM/automation-ibmcloud-infra-openshift/tree/main/1-quickstart/200-openshift-gitops), I encounter the following errors:

Error: External Program Execution Failed

先从所引用的 .terraform/modules/*/scripts/setup-binaries.sh 和 main.tf 中的外部数据源开始，然后检查 igc-linux release 是如何下载并由 local-exec provisioner 调用的。当基于 M1 的 Multipass VM 能够应用 105 和 200 层，且不会出现下载失败或 igc“Exec format error”时，即表示完成。
