### Apache Airflow version

2.6.2

### What happened

I left this as a TODO and will get t it eventually, but if someone wants to look into it before I get time, this may be an easy one:

We are creating an OTLPMetricExporter endpoint with `http` [here](https://github.com/apache/airflow/blob/main/airflow/metrics/otel_logger.py#L400) and should look into whether we can make this work with `https`.


### Definition of Done:
Either implement HTTPS or replace the TODO with a reference citing why we can not.


I am submitting this as an Issue since I will be a little distracted for the next bit and figured someone may be able to have a look in the meantime. Please do not assign it to me, I'll get it when I can is nobody else does.
