Support file scoped namespace declarations when generating code

[304NotModified]

🤔 What's changed?

Generated file scoped namespaces when set in .editorconfig

Normally "create" generates this:

namespace MyNamespace.StepDefinitions
{
    [Binding]
    public class CalculatorStepDefinitions
    {
        [Given("the first number is {int}")]
        public void GivenTheFirstNumberIs(int p0)
        {
            throw new PendingStepException();
        }

With

# C# files
[*.cs]
csharp_style_namespace_declarations = file_scoped:suggestion

We get this:

namespace MyNamespace.StepDefinitions;

[Binding]
public class CalculatorStepDefinitions
{
    [Given("the first number is {int}")]
    public void GivenTheFirstNumberIs(int p0)
    {
        throw new PendingStepException();
    }

In VS config:

⚡️ What's your motivation?

Keep the code style from the editorconfig.

This is ready for review. I tested it locally and added snapshot tests :)

I've scanned it through and it looks cool! I'll make a more detailed review during my holidays.

@gasparnagy polite bump. FYI I have tested this locally

Yes, sorry for the delay. It's on my list... Pretty busy for the rest of the week, so can check probably next week only.
