Update Helix ubuntu arm32 container

[ericstj]

Looks like the 18.04 containers were removed in dotnet/dotnet-buildtools-prereqs-docker@fd83c7a#diff-575b0b833a9ff8e4d19b4197fd33b06ba348c24a137f7313fb9be82c8e3feb10

We're now seeing helix failures running tests. Let's update to fix those.

Seeing other usage of 18.04 in our build containers as well, but these aren't failing right now. Also couldn't find the same cross images in the new set - and changing build container can result in dropping support for those older versions, so we should make sure we do the right thing.

I think we'll still need dotnet/dotnet-buildtools-prereqs-docker#1374 to fix this, but we'll also need this PR since the container we were using is no longer updated.

Seems the new images are broken, but with a new problem:

System.Security.Authentication.AuthenticationException : The remote certificate is invalid because of errors in the certificate chain: NotTimeValid

Seeing this for multiple different servers: nuget.org, openaipublic.blob.core.windows.net - and the same tests pass when run on other images - most likely not a server problem.

Time logged by the test looks accurate - so it would seem that it's not a case of client disagreeing with server on time (though that's a guess).

It looks like we can't use Ubuntu 24.04 for testing with .NET 8 on ARM32 because of dotnet/core#9285.

We need a different container for testing ARM32. Ubuntu 22.04 would work, but it seems this is not provided by https://github.com/dotnet/dotnet-buildtools-prereqs-docker/blob/main/src/ubuntu/manifest.json. I'm asking folks for a recommendation.

I have a PR to get this added for 22.04: dotnet/dotnet-buildtools-prereqs-docker#1381
