Installing GitHub Copilot CLI from scratch results in v1.0.5

[jovere]

Describe the bug

Installing copilot CLI from scratch results in only getting v1.0.5, not the latest version.

This is an issue, since I have a docker image specifically for Copilot. Every time copilot is run, a new container is created. That means every time I run copilot, I need to update.

Affected version

latest

Steps to reproduce the behavior

1. Create a new docker image containing copilot cli, using the following dockerfile:

# Use a slim Node.js base image, which gives us `npm`.
FROM node:22-slim

# Set non-interactive frontend to avoid prompts during package installation.
ENV DEBIAN_FRONTEND=noninteractive

# Install git, curl, gpg, and gosu for the entrypoint script.
RUN apt-get update && apt-get install -y \
  curl \
  gpg \
  git \
  gosu \
  && rm -rf /var/lib/apt/lists/*

# Install the standalone GitHub Copilot CLI via npm.
RUN curl -fsSL https://gh.io/copilot-install | bash

# Set the working directory for the container.
WORKDIR /work

# The default command to run if none is provided.
CMD [ "copilot", "--banner" ]

3. Start the image.
4. Observe that the version is 1.0.5

Expected behavior

The copilot version after image creation will be the latest.
