Issue in /main/src/pages/getting-started/personalization.md

This is the only document which describes how personalization on the Edge Network is configured, but it does not go into depth on how "Customer Personalization Connections" (CPC) are configured. Nor does the CPC documentation found here - https://experienceleague.adobe.com/en/docs/experience-platform/destinations/catalog/personalization/custom-personalization

Neither document describes that the "decisionScopes" parameter is required to get a CPC response for a CPC.

To get this to work the decisionScopes parameter must be set to the alias value that was configured as part of a CPC.

i.e. the following type of payload should be added to and Edge Network request expecting a CPC response.

```
"query": {
"personalization": {
"decisionScopes": [""]
}
}
```

Because this was not explained in the docs I had to go to an external source to find it out.

Read main/src/pages/getting-started/personalization.md and compare its Edge Network personalization guidance with the linked Customer Personalization Connections documentation. Add the required decisionScopes parameter and destination-alias example; the issue is done when CPC configuration and the request payload are clearly documented.
