Any concerns about not paginating here? I'm not sure how many teams we return per page, but I'm guessing sooner or later we will come across someone who has hundreds of them.

Claude flagged the fact that every time someone updates a team, it's going to set members_can_create_pipelines: false even if the current setting for that team is true. "Balderdash," said I. "Prove it!" So we looked at go_buildkite, where it turns out that the Team struct doesn't include all the fields that the API returns, including MembersCanCreatePipelines. And then looking upstream at the API in Team::Updater and how it would handle this, it looks like it would in fact apply the false flag and change the setting unexpectedly. We'd need to fix this in go_buildkite and then here do MembersCanCreatePipelines: current.MembersCanCreatePipelines,

If this makes sense to you, I can throw the PR at go_buildkite and then add a commit to this.

I think false is a sensible default? It's definitely safer than true and would still allow for creation of the team but with safeguards in place.

Discussed in Slack - we still need to fix go_buildkite to avoid us forcibly changing this setting when we update teams. That'll be a separate task.
