DEV: Snapshot Submission Email Template to DRO

### Dependency
- https://github.com/hackforla/tdm-calculator/issues/2437

### Overview
This email is sent to the DRO when a user submits a snapshot. The goal is to notify the DRO staff member and give them a direct entry point into the app using the project ID to review the submission.

### Details
- only admins can access the Manage submission page
- Email subject : New Snapshot Submission for DRO: {DRO NAME}
- Include the Project ID in the email body.
- The link of the Manage Submissions button encodes the project ID in the URL and goes to the Manage Submissions page with the results pre-filtered to the Project ID
