Add additional thoughts on rolling out breaking changes

Today we talked about how to roll out breaking changes safely in the octokit.js ecosystem. This PR captures that discussion in a more durable place.

It may be good to note that for changes requiring type changes, @octokit/types needs to be updated

[kfcampbell]

Good idea @wolfy1339! Would that go at the top of the chain since it's a dependency of many other modules?

[wolfy1339]

That sounds right

I've updated the list accordingly!
