Feature Request - Option to Nest Solution in a folder

As the option `Create a Solution File` creates a solution in the current directory, it would be nice if there was also an option to nest this solution in a folder of the same name. (same as how the project is generated inside of a folder)

E.g. the output would then be:
```
MyProject/
├─ MyProject.sln
├─ MyProject.Web/
│  ├─ MyProject.Web.csproj
```
