Feature Request: generate a comparison github link when the changelog is unavailable

[lemeurherve]

Is your feature request related to a problem?

When the changelog of a repository is unavailable, we have to go to the repository to try to find the changes between versions.

Solution you'd like

If there is no changelog available we could add a comparison url like the one in hadolint changelog: https://github.com/hadolint/hadolint/compare/v2.9.2...v2.9.3

https://github.com/org/repo/compare/v{{ previousVersion }}...v{{ currentVersion}}

Also, putting this link outside the changelog block would allow clicking on it directly.

I like this idea very much

I fear retrieving and storing the original value to generate this URL won't be that easy, AFAIU it's never stored anywhere.

Let's keep this request open though: while implementing the actions, I've just met this challenge and I might have a way to do it (except maybe for shell resources) as part of the "dry run".

It won't be trivial but necessary, I have been thinking about this for quite some time and I see different way to solve this but indeed @dduportal refactoring with action may influence the solution.
