Describe the bug
Response components are incorrect for GET /v3/customers/{customerId}/metafields and GET /v3/customers/{customerId}/metafields/{metafieldId}

To Reproduce

1. Go to https://developer.bigcommerce.com/docs/rest-management/customers/metafields#get-customer-metafields
2. Scroll to Response and note the shape of Body for the 200 response (object with property items)
3. Make a GET request to https://api.bigcommerce.com/stores/{store_hash}/v3/customers/{customerId}/metafields for any valid store_hash and customerId
4. Compare the runtime response shape (object with property data) to the shape in the documentation
5. Repeat the above for https://developer.bigcommerce.com/docs/rest-management/customers/metafields#get-a-customer-metafield and https://api.bigcommerce.com/stores/{store_hash}/v3/customers/{customerId}/metafields/{metafieldId}

Expected behavior
Response components in the documentation should match what is received at runtime.
