Generate OS package for aarch64 and let sdkman know

[mkurz]

sdkman doesn't know about the aarch64/arm64 binary yet 😢
This is what I get on my aarch64 Linux:

$ sdk install scalacli

Stop! scalacli 0.1.19 is not available. Possible causes:
 * 0.1.19 is an invalid version
 * scalacli binaries are incompatible with your platform
 * scalacli has not been released yet

Tip: see all available versions for your platform:

  $ sdk list scalacli

$ sdk list scalacli

@lwronski Finished, it should work now. Here you can see the artifacts generated also with the sdk packages for aarch64: https://github.com/VirtusLab/scala-cli/actions/runs/3897030762 This was the last run, I just squashed the commit now and removed added back the if: github.event_name == 'push', so the generate-linux-arm64-native-launcher doesn't run for PRs, because it takes ages.
I tested the artifacts of the sdk aarch64 package and it works now.

Should be ready to merge.

CI is green now as well.
