Can't find runtime on Amazon Linux EC2 instance

[attilah]

Describe the bug Tried to run dotnet serve on a x64 AL EC2 instance and run into issues.

.NET SDK 8 and runtime is installed and confirmed working.

To Reproduce Steps to reproduce the behavior:

1. Launch an EC2 instance with x64 architecture and Amazon Linux
2. Install .NET 8 with the MSFT shell script as suggested
3. Install dotnet serve
4. Update .bashrc as requested
5. Make sure dotnet functions correctly with dotnet --list-sdks and dotnet --list-runtimes
6. Run dotnet serve in a directory.

Expected behavior dotnet serve starts

Seems like an issue with .NET that would affect all CLI tools, not just this one, right? Or is there some kind of new packaging thing that breaks with .NET 8?
