Subject: [PATCH 1/2] fix(crons): Add trailing slash to monitor environment
 detail endpoints

The project and organization monitor environment detail endpoint URL
patterns were missing trailing slashes, causing 404 responses when
requests included trailing slashes. This resulted in CORS preflight
failures as only the OPTIONS method was reported as allowed.

Fixed both URL patterns to accept trailing slashes:
- sentry-api-0-project-monitor-environment-details
- sentry-api-0-organization-monitor-environment-details
