Support team assignment for cron monitors via SDK

[julwhitney13]

Problem Statement

When creating cron monitors via sentry_monitor(), there's no way to assign the monitor to a team. Currently, team ownership must be set manually through the Sentry UI or via a separate API call after the monitor is created.

Solution Brainstorm

Add support for team assignment in the MonitorConfig TypedDict so monitors can be assigned to teams programmatically:

monitor_config = {
    "schedule": {"type": "crontab", "value": "0 7 * * *"},
    "checkin_margin": 5,
    "max_runtime": 30,
    "timezone": "UTC",
    "team": "my-team-slug"  # or team_id
}

  with sentry_monitor(
      monitor_slug="my-cron-job",
      monitor_config=monitor_config
  ):
      execute_job()

For teams managing a lot of cron jobs (and multiple teams that all own different cron jobs) auto-assigning monitors to the right team during creation improves:

• Discoverability (team members see their jobs automatically)
• Ownership clarity and triaging of alerts
• Automation (no manual UI steps post-deployment)

Thanks!
