Sam Build fails when publishing against dotnet8 runtime

[mldasco]

Description:

sam build fails after I upgrade to my solution to dotnet8 runtime. Downgrading back to dotnet6 runtime works.
Problem seems to be that upon publishing it's working folder is set to /net6.0/ rather than /net8.0/

Steps to reproduce:

1. Start with .net project with <TargetFramework>net6.0</TargetFramework>
2. Update csproj files to <TargetFramework>net8.0</TargetFramework>
3. Update template.yaml file to Runtime: dotnet8
4. Run sam build --debug and observe build failed
