Cannot create project when migrating from cloud to self-hosted

### 👟 Reproduction steps 1. Install Appwrite 1.8.1 (or 1.8.0) self hosted 2. Go to your cloud project 3. Hit Settings > Migrations > Export to self-hosted instance 4. Set the "Endpoint self-hosted instance URL" 5. Get redirected and set a new name for the new project to be created 6. Click "Next": Error raises: "**Invalid region param: Value must be one of (default)**" - This happens before selecting which ressource to migrate - Using an existing project does not fail with this error - The problem occurs either within an organization or personal projects ### 👍 Expected behavior The project is migrated successfully from Cloud to Self-hosted instance. ### 👎 Actual Behavior The migration instantly fails with the following error: "**Invalid region param: Value must be one of (default)**". Appwrite containers logs when the error occurs: `appwrite | [Error] Method: POST appwrite | [Error] URL: /v1/projects appwrite | [Error] Type: Utopia\Exception appwrite | [Error] Message: Invalid `region` param: Value must be one of (default) appwrite | [Error] File: /usr/src/code/vendor/utopia-php/framework/src/App.php appwrite | [Error] Line: 910` ### 🎲 Appwrite version Version 1.8.x ### 💻 Operating system Linux ### 🧱 Your Environment _No response_ ### 👀 Have you spent some time to check if this issue has been raised before? - [x] I checked and didn't find similar issue ### 🏢 Have you read the Code of Conduct? - [x] I have read the [Code of Conduct](https://github.com/appwrite/.github/blob/main/CODE_OF_CONDUCT.md)
