Move dotnet8 AOT to the dotnet runtime

[Beau-Gosse-dev]

We're recommending people deploy .NET 8 Native AOT projects to the .NET 8 managed runtime (instead of Al2 or AL2023). Since it will have the needed libraries available (like libicu). It also removes the need for the assembly name requirement of bootstrap and brings billing inline with managed runtimes.

PR https://github.com/maxday/lambda-perf/pull/935/ added AL2 and AL2023.

Can we replace provided.al2 with dotnet8?
