Feature request: add repo link to update notifer

[shrpne]

It would be useful to add repository or changelog link to the notification generated by update-notifier

It can be done with custom message option as described here yeoman/update-notifier#213 (comment)

Hi, thanks for the suggestion.

Given that I only add change log notes for major version releases, I think I would prefer without the link. If there was a way to provide a direct link to the release notes only when they exist, I would be open to that.

May be just the link for the repository then? So user can investigate what is changed

I have given this further consideration, and figured out a way to provide useful information for both major and non-major upgrades without having to change my changelog policy.

Major updates link to the release notes:

╭────────────────────────────────────────────────────────────────────────────╮
│                                                                            │
│                      Update available 15.3.4 → 16.0.0                      │
│                  Run npm i -g npm-check-updates to update                  │
│   https://github.com/raineorshine/npm-check-updates/releases/tag/v16.0.0   │
│                                                                            │
╰────────────────────────────────────────────────────────────────────────────╯

Major updates across multiple major versions link to each major version's release notes:

╭────────────────────────────────────────────────────────────────────────────╮
│                                                                            │
│                      Update available 13.0.0 → 16.3.1                      │
│                  Run npm i -g npm-check-updates to update                  │
│   https://github.com/raineorshine/npm-check-updates/releases/tag/v14.0.0   │
│   https://github.com/raineorshine/npm-check-updates/releases/tag/v15.0.0   │
│   https://github.com/raineorshine/npm-check-updates/releases/tag/v16.0.0   │
│                                                                            │
╰────────────────────────────────────────────────────────────────────────────╯

Non-major updates link to a list of commits between current and latest:

╭─────────────────────────────────────────────────────────────────────────────────╮
│                                                                                 │
│                        Update available 16.2.0 → 16.3.1                         │
│                    Run npm i -g npm-check-updates to update                     │
│   https://github.com/raineorshine/npm-check-updates/compare/v16.2.0...v16.3.1   │
│                                                                                 │
╰─────────────────────────────────────────────────────────────────────────────────╯

Published in v16.3.2
