Use common packages from monorepo

[vearutop]

Description

This PR changes imports of messages and gherkin to use common monorepo.

Motivation & context

Pros:

• A small change to godog
• Code coverage and lint are not affected

Cons:

• Runtime double dependency on a large repo (one copy for gherkin/go/v20 and one for messages/go/v17)
• Every further change of imports (e.g. to messages/go/v18) is technically a breaking change for godog as end-users may depend on messages directly while implementing advanced step definitions.

Runtime dependency on a monorepo seems like not a big deal, for example in GitHub Actions those packages are retrieved in 1-2 seconds.

Resolves #389.

Type of change

• Refactoring/debt (improvement to code design or tooling without changing behaviour)
• Breaking change (will cause existing functionality to not work as expected)

@vearutop Sorry it's taken me so long to give you feedback on this and #428.

One bit of context that might affect this is that we've decided to break up the monorepo, so the burden on users of downloading the dependencies will be much smaller once that's done.

Do you have a favourite of the two?

Note that messages is well on the way to being removed.

Closing this, as we need to migrate to different standalone modules (https://github.com/cucumber/common/issues/2029).
