Inconsistent Metric Descriptions Between `dockerstatsreceiver` and `podmanstatsreceiver` Causing `prometheusexporter` Errors

Component(s)

receiver/podman

What happened?

I am using dockerstatsreceiver and podmanstatsreceiver simultaneously, but there are inconsistencies in some of the metric descriptions between them. This results in errors from the prometheusexporter (see log output for details).

Differences can be observed here:

Collector version

0.111.0
