[FEAT]: Provide command to upgrade extension as part of the 'A new release of gh-copilot is available' notification

[Glenn 'devalias' Grant]

Describe the need

When the extension reports that a new version is available, it would be nice if it also gave me an easily copy/pasteable command to update to that new version.

Currently it shows this:

A new release of gh-copilot is available: 1.0.0 → 1.0.1
https://github.com/github/gh-copilot/releases/tag/v1.0.1

Ideally it would show something like this so I don't have to remember how the CLI works and/or go and look at the --help every time:

A new release of gh-copilot is available: 1.0.0 → 1.0.1
https://github.com/github/gh-copilot/releases/tag/v1.0.1

To upgrade, run: gh extension upgrade gh-copilot

Version

Observed on 1.0.0

Relevant terminal output

See above.

@0xdevalias : not a bad idea, I like it. 🤔

Here's the specific format of the gh 'update available' text, may be cool to match it:

A new release of gh is available: 2.46.0 → 2.47.0
To upgrade, run: brew upgrade gh
https://github.com/cli/cli/releases/tag/v2.47.0

In the meantime, how do I update the copilot extension manually? I'm on Windows.
