Bug: Amd64 installed instead of arm

[pkruk]

What happened?

Hi,

We use a github runner based on arm64 in aws, and when we start using this action, we got a strange error:

Helm tool version: 'v3.11.3' has been cached at *_tool/helm/3.11.3/arm64/linux-amd64/helm

It's looks like that actions is downloading the incorrect version according to my architecture:

uname -m
aarch64

Native script get_helm.sh is working as shine, so it's looks there is a problem in node-script:

   const arch = os.arch()
   const operatingSystem = os.type()

   switch (true) {
      case operatingSystem == LINUX && arch == ARM64:
         return util.format(
            'https://get.helm.sh/helm-%s-linux-arm64.zip',
            version
         )

not sure if the os.arch is returning in this case aarch64 instead of arm64, so the condition in switch is incorrect.

Version

• I am using the latest version

Runner

self-hosted, linux, arm64 (graviton aws)

Relevant log output
