add support for arm64 Helm binaries.

[dcasati]

add a condition to check what architecture we will be executing Helm (arm64 or amd64). This will ensure that we download the correct binaries for that platform. Currently, on a arm64 Mac (M1/M2 processors) we are downloading the amd64 helm binary and are using Rosetta for the translation. This breaks on any other OS (e.g.: Linux) running on aarch64.

this is a WIP as the https://k8connecthelm.azureedge.net/helm/ only contains the amd64 version of helm.

connectedk8s adds support for arm64

[XavierGeerinck]

Any update on this? (friendly ping @yonzhan)

Note: a workaround is possible by creating a symlink to the correct HELM binaries

curl https://raw.githubusercontent.com/helm/helm/main/scripts/get-helm-3 | bash -s -- -v v3.6.3
sudo mv ~/.azure/helm/v3.6.3/linux-amd64/helm ~/.azure/helm/v3.6.3/linux-amd64/helm-old
ln -s /usr/local/bin/helm ~/.azure/helm/v3.6.3/linux-amd64/helm

@akashkeshari Could you please help review the connectedk8s extension related PR?

[bebound]

@akashkeshari CLI will support ARM64 in 2.46.0.
It would be great if this extension can also work on ARM64.
