docs(exporters): replace 'collector' with 'OTLP compatible receivers'

[pichlermarc]

Which problem is this PR solving?

Addresses comment

Not related to this fix, but I think the wording should be "OTLP receiver" instead of "opentelemetry-collector", since the exporter >can send to any OTLP compatible receiver.
