The metadata generator doesn't support histogram metrics

What happened?

Description

I am writing a component that generates histogram metrics. While writing its metadata.yaml, mdatagen failed because only gauges and sums are supported. This can be checked in the schema here.

Steps to Reproduce

Add histogram metrics in any metadata.yaml file and run mdatagen.

Expected Result

Metadata files should be generated.

Actual Result

mdatagen fails with the following error:

* error decoding 'metrics[apm.service.transaction.duration]': 1 error(s) decoding:

* '' has invalid keys: histogram
doc.go:4: running "mdatagen": exit status 1

Collector version

v0.83.0
