Fixes #37024

Testing

[atoulme]

@pjanotti would you please review? Some CI failures are happening for both 2022 and 2025. I also see main failing.

[pjanotti]

Group receiver-3 seems to be failing consistently on main too. I still have to look at the other failure (at first not happening in main).

[songy23]

Test failures are unrelated to this PR: #10151, #36917

[pjanotti]

statsdreceiver failures are related to PR #36608 which introduces Unix Datagram support for the receiver, but, didn't skip the new tests on Windows.

[pjanotti]

Fix for statsdreceiver: #37036

[pjanotti]

#36923 fixes the other failures for receiver-3 group.

[pjanotti]

The error in exporter-3 group seems, at first, a concurrent behavior slightly different on Windows 2025. It seems that the test itself should ensure that the server used in the test is operational before blasting the concurrent requests.

[pjanotti]

@CodePrometheus apply the following patch to your change to fix the exporter-3 group failures (assuming that my hypothesis is right)

Actually this one is fine to use windows-latest since it is building the binary, we should be fine with windows-latest - it also breaks because it tries to upload two artifacts with the same name.

[pjanotti]

@CodePrometheus (or someone with the rights) could you please merge latest main to clean up the CI failures that were unrelated to this PR?

[pjanotti]

It seems that my suggestion at #37025 (comment) wasn't enough to fix the concurrency issue on Windows 2025... 🤔
