Merging prior to a full work day as this is a previously communicated change that the community agreed upon.

@MrAlias it seems that you forgot to update the README; it still contains

[Exporters](https://github.com/open-telemetry/opentelemetry-go-contrib/blob/main/exporters): Packages providing OpenTelemetry exporters for 3rd-party telemetry systems.

Thanks! I'll include a fix in #1921

Hey heads up to say that this broke links in an AWS blog that is still linked from their main feature page under "how to ship metrics to AMP": https://aws.amazon.com/blogs/opensource/building-a-prometheus-remote-write-exporter-for-the-opentelemetry-go-sdk/

Linked here: https://aws.amazon.com/prometheus/features/

To learn more about writing your own client to use remote write, see Building a Prometheus remote write exporter for the OpenTelemetry Go SDK.

No idea if any of the contributors to that blog are likely to see this to help fix that but just wanted to call it out in case others are hunting around! If not I can see if that can be brought up with AWS folks somehow.

I found the deprecation note in the files removed. Repeating here for anyone who might find this and wonder why:

⚠️ This project is deprecated. Use the go.opentelemetry.io/otel/exporters/otlp/otlpmetric exporter as a replacement to send data to a collector which can then export with its PRW exporter.
