Issue Description

After updating our first apps to .NET 8 I once again stumbled over the ancient messages writen by DotNetCoreCLI@2 about .NET 2.2, 3.0 and 5.x.

We are using Azure DevOps Server in latest version and use only support .NET runtimes/SDKs. Our Devs ask every than and now why these messages still pop up.

I would like to see this message removed or at least give us an environment variable (e.g. SKIP_HOSTED_AGENT_INFOS) to skip these messages

Info: .NET Core SDK/runtime 2.2 and 3.0 are now End of Life(EOL) and have been removed from all hosted agents. If you're using these SDK/runtimes on hosted agents, kindly upgrade to newer versions which are not EOL, or else use UseDotNet task to install the required version.
"C:\Program Files\dotnet\dotnet.exe" tool restore
Tool 'dotnet-ef' (version '8.0.0') was restored. Available commands: dotnet-ef

Restore was successful.
Info: Azure Pipelines hosted agents have been updated and now contain .Net 5.x SDK/Runtime along with the older .Net Core version which are currently lts. Unless you have locked down a SDK version for your project(s), 5.x SDK might be picked up which might have breaking behavior as compared to previous versions. You can learn more about the breaking changes here: https://docs.microsoft.com/en-us/dotnet/core/tools/ and https://docs.microsoft.com/en-us/dotnet/core/compatibility/ .
