Fix command in v2 example (#6134)

## Which problem is this PR solving?
The `component.UseLocalHostAsDefaultHost` gate has been removed from
otel collector since v0.112.0. The example failed to start `jaeger`
because of the invalid argument.

## Description of the changes
- Remove the invalid command line argument.
- Set endpoints for `otlpreceiver` explicitly.
