Provide hasura-cli as an alpine package (apk)

### Is your proposal related to a problem?

I'd like to have a native alpine package for hasura-cli, so that I can download it from https://pkgs.alpinelinux.org/packages

### Describe the solution you'd like

`apk --update add hasura-cli`

### Describe alternatives you've considered

Currently using `curl` to download from github

### If the feature is approved, would you be willing to submit a PR?

no

The issue names no files, tests, or repository entry points. Start by reviewing how hasura-cli is released and how Alpine packages are submitted; done means an Alpine package is available through pkgs.alpinelinux.org and installs with `apk --update add hasura-cli`.
