Status Page API no longer includes maintenance window status

**Describe the bug**
In v3.2, the API endpoint for status pages would include information about if a maintenance window existed for a monitor, with a property of `isMaintenance` under each monitor. After updating to v3.3, this field is no longer returned in the API response.

**To Reproduce**
Steps to reproduce the behavior:
1. Send a `GET` request to `https://checkmate-demo.bluewavelabs.ca/api/v1/status-page/179630?type=uptime`
2. Refer to `data.monitors[].isMaintenance`

**Expected behavior**
In v3.2, the field will exist as a boolean, indicating if a maintenance window has been created for this monitor. In v3.3, the field is missing.
