NewTeam missing notification_setting field

[ggabijaa]

When creating a new team Github API let's to disable notifications for the team by setting notification_setting to notifications_disabled.
https://docs.github.com/en/rest/teams/teams?apiVersion=2022-11-28#create-a-team

However, this field is missing from NewTeam struct and prevents disabling it
https://pkg.go.dev/github.com/google/go-github/v60@v60.0.0/github#NewTeam

Would it be possible to add it?
