chore(ec2): invalid Interface VPC Endpoints (#31441)

### Issue # (if applicable)

None

### Reason for this change

The wrong URLs were set for several Interface Endpoints, so I corrected them.

For example, when retrieving the freetier endpoint via CLI, it shows as `aws.api.{region}.freetier`, but in CDK, it was set to `com.amazonaws.{region}.freetire`.

I believe this correction might be a breaking change, but since the previous URLs likely wouldn't have allowed access anyway, I'm unsure how to proceed. Which of the following approaches would be best?

- Directly fix the incorrect URLs (the current implementation)
- Implement a feature flag
- Deprecate the existing method and implement a new one

### Description of changes

Update URL from `com.amazonaws.{region}.{service}` to `aws.api.{region}.{service}`

- freetier
- bcm-data-exports 

### Description of how you validated changes

I've executed `described-vpc-endpoint-services` CLI.

```sh
❯ aws ec2 describe-vpc-endpoint-services --filters Name=service-type,Values=Interface Name=owner,Values=amazon --region us-east-1 --query ServiceNames | grep aws.api
    "aws.api.us-east-1.bcm-data-exports",
    "aws.api.us-east-1.freetier",
    "aws.api.us-east-1.kendra-ranking",
    "aws.api.us-east-1.qbusiness",
```
