Provide linux/arm64 image for alpine

[harryzcy]

Summary of the new feature / enhancement

super-linter is preparing for arm64 support super-linter/super-linter#5070. It would be very helpful to have a alpine arm64 docker image.

Proposed technical implementation details (optional)

To have the musl-based arm64 release of PowerShell first: PowerShell/PowerShell#24552

Jason Helmick (@theJasonHelmick) We consume super-linter in https://github.com/PowerShell/PowerShell. So it would be helpful for PowerShell project to complete this issue.
