feat(ci): for each release set link to diffs between the release and the geth corresponding release

[qdm12]

Example link: 0b56af5...ava-labs:libevm:v1.13.14-0.1.0.rc-2

Workflow to modify: https://github.com/ava-labs/libevm/blob/main/.github/workflows/libevm-delta.yml

Re "workflow to modify", are you thinking about having it automated?

[qdm12]

Yes 😉

It would be nice to:

1. Find automatically the most recent commit common to go-ethereum and libevm (with git/github api/exiting github action)
2. Add automatically to the release notes the link at the top or bottom https://github.com/ava-labs/libevm/compare/<most-recent-commit-common-with-geth>...vX.Y.Z (might be an existing github action for this too)

Not a priority though, we can do this manually in the meantime.
