Add support for the linux-arm64 architecture

[robandpdx]

This extension does not support the linux-arm64 architecture. I tried to install it on a linux-arm64 machine, and it failed due to the lack of an available binary. Would you be able to update the extension's build and release process to include the relevant binary? For more details, see https://docs.github.com/en/github-cli/github-cli/creating-github-cli-extensions.
