Fix missing API notification flags for Microsoft Teams

What does this MR do?

Partially solves #59702 (closed), which was already partially solved by !29736 (merged).

GitLab API currently doesn't accept the notify_only_broken_pipelines or notify_only_default_branch options for the Microsoft Teams service, apparently because it was left out in !11435 (merged). This MR just adds those flags to the Microsoft Teams API definition.
