Is the Gauge introduced in dotnet 9 not supported now?

[WeihanLi]

When I try to use Meter.CreateGauge to create a gauge, seemed the metrics not exported as expected, when I use the Counter, it works as expected

sample code for repro:

https://github.com/WeihanLi/SamplesInPractice/blob/main/net9sample/Net9Samples/MetricsSample.cs

and the package version I used is 1.9.0

seeing #5867 would this be released in the next version 1.10.0?

Think it's a yes, and would be released when dotnet 9 released
