[SCENARIO] Dropped Links

Add a new scenario when https://github.com/open-telemetry/opentelemetry-collector/pull/14217 is merged to emit a trace with dropped links.

I've also raised (https://github.com/open-telemetry/opentelemetry-proto/issues/745) that the documentation about when / why things are "dropped" is either incomplete or hard to find so it's hard for end users to understand why an event might be dropped.

## Example JSON

I think the trace would look like this, but not sure until the above PR is merged.

```
{
"traceId": trace_id,
"spanId": secrets.token_hex(8),
"name": "span",
"kind": "SPAN_KIND_UNSPECIFIED",
"start_time_unix_nano": span_start_time,
"end_time_unix_nano": span_end_time,
"droppedAttributesCount": 0,
"attributes": [],
"events": [],
"droppedEventsCount": 0,
"droppedLinksCount": 31,
"status": {
"code": get_span_status_int("OK")
}
}
```
