Monitor command fails with DSN auth

[philipphofmann]

Environment

sentry-cli 2.16.0

Steps to Reproduce

I tried to switch to the DSN authentication in getsentry/apple-system-symbols-upload#20 for uploading apple system symbols.

1. Export DSN as environment variable as explained in the docs
2. Call sentry-cli monitors run 430ded42-54cb-427b-8fc7-433ac9ca8da5 -- python3 import_system_symbols_from_simulators.py

Expected Result

sentry-cli should run the monitor command as previously with the auth token.

Actual Result

sentry-cli fails with

error: API request failed
  caused by: sentry reported an error: request failure (http status: 400)
  Object ***"status": Array [String("This field is required.")]***

The command still worked with 2.15.2, so we pin (getsentry/apple-system-symbols-upload#21) the version for now.
