Consider inspecting diff for package updates

[jamesbirtles]

It seems like (at least for group updates) the PR body that dependabot is outputting changes fairly frequently. Its already changed twice since releasing this action.

It would be great to look into reading the package.json diff to figure out changes instead as that format is not really going to change.
