Linux machines need to install ICU in order for aspire.exe to work

If you install aspire on a fresh `ubuntu:24.04` machine you get the following error:

```
Aspire CLI successfully installed to: /root/.aspire/bin/aspire
Warning: Failed to set global config via aspire CLI: Process terminated. Couldn't find a valid ICU package installed on the system. Please install libicu (or icu-libs) using your package manager and try again. Alternatively you can set the configuration flag System.Globalization.Invariant to true if you want to run with no globalization support. Please see https://aka.ms/dotnet-missing-libicu for more information.

Is there a route we could take that doesn't need this dependency?

Start by reproducing the Aspire CLI installation and configuration failure on a fresh ubuntu:24.04 machine, using the reported aspire.exe path and stack trace as the entry point. Determine whether the CLI can avoid ICU or must require it; done means the installation and configuration step works as described without the reported failure, or the dependency requirement is made explicit.
