Add multi-byline fields

[simonbyford]

What does this change?

This adds support for the new fields included in Multi-byline fields.

These fields have been available content-api-client since v33.0.0.

dotcom-rendering is already able to render these fields, since guardian/dotcom-rendering#12496

@simonbyford I think we'll need to bump content-api-scala-client in facia-scala-client, and then bump facia-scala-client here, to get the build to pass.

Who knew dependency cascades weren't just a JavaScript problem 😄

I've raised a PR: guardian/facia-scala-client#341

Ah hello! Sorry I missed this PR, I think I may have duplicated your work a bit as I've opened #27705 - actually that PR is only bumping CAPI & FAPI client versions, not adding the additonal code you've added around reading the multi-author bylines in PageElement.scala.

We might want to stack this PR on top of #27705, what do you think?

I don't mind! Happy to keep them separate if yours is likely to be merged soon? Then I can just rebase
