Modified the F# Template so that GitVersionInformation is a static class and not a module anymore

[odalet]

Description

• Modified the F# template:
  • Added namespace global at the top of the file (it seems to required for types but not modules)
  • Changed the module into a type decorated with AbstractClass and Sealed and with no constructor so that it generates a static class.
  • Changed the per-property template: replaced the let expressions with static member definitions.

NB: I didn't add the extra attributes I described in #2311 to property getters. They seem a lot of boilerplate and not useful at all.

Fixes #2311

Motivation and Context

These changes have the F# compiler generate less code behind the scene, hence this is more code coverage-friendly.

How Has This Been Tested?

• Fixed the unit tests
• Ensured the resulting type could be quieried through reflection (beware; in this F# case we need look for properties, not fields) both with C# and F# code (see ReflectionTests and ReflectionTestsFS in https://github.com/odalet/GitVersionTests)
• Double-checked the results in ILSpy:

// GitVersionInformation
using Microsoft.FSharp.Core;
using System;
using System.Diagnostics.CodeAnalysis;
using System.Runtime.CompilerServices;

[Serializable]
[AbstractClass]
[Sealed]
[CompilerGenerated]
[ExcludeFromCodeCoverage]
[CompilationMapping(/*Could not decode attribute arguments.*/)]
public static class GitVersionInformation
{
	public static string Major => "1";

	public static string Minor => "2";

	public static string Patch => "3";

        ...
}

No more weird $GitVersionInformation type:

Thanks for merging!

This PR, though, like #2313, suffered from the 'dotnet format' failing check too... I wanted to fix this soon, but it seems it automagically fixed itself :-)
