Reviewers: I would like to draw your attention on the gherkin changelog, as there may be kinda undesired changed with gherkin-streams

This seems like the right change to me. gherkin-streams lists message-streams as a peer dependency so it's expressed correctly - although I do think we should add an Installation section to the readme there and explicitly call out the peer dependencies.

Also I think the plan is for gherkin to be decoupled from messages, right? So this should be short-lived anyway.

You mean, the Installation section of gherkin-streams?

Sorry - yes exactly.
