bazelisk completion fails on arm64

bazel commands work correctly on arm but bazelisk completion fails to pull an installer script that doesn't exist.

bazelisk completion bash > bash-complete.bash

The real fix would be for Bazel to publish an installer for Linux arm64. What we can do here is to improve the error.

Any idea why only this command fails but build and test work fine?

[fweikert]

It's a fundamentally different command - for build and test Bazelisk just calls Bazel.

The completion command is unique to Bazelisk. It extract the bash completion data from the installer scripts that are part of Bazel releases (e.g. the "installer" files at https://github.com/bazelbuild/bazel/releases/tag/8.2.1).

However, there are currently no installer scripts for Linux arm64, that's why the command fails when running on this platform.
