Installs the gh copilot suggest and gh copilot explain aliases as per the official GitHub Copilot in the CLI documentation, but for the Fish shell as it's not natively supported by the upstream.
fisher install rcny/gh-copilot-cli-alias.fish
Copy conf.d/gh-copilot-cli-alias.fish from this repository to your local $__fish_config_dir/conf.d directory.
The aliases provided are ghcs and ghce, which behave in the same way as officially generated aliases for any supported shell.
