AutoActions for Skinny controllers-documentation improvements

One improvement is to move  Initialize in other partial class. . It was difficult every time I need to activate the debugger

public void Initialize(GeneratorInitializationContext context)
         {

            context.RegisterForSyntaxNotifications(() => new SyntaxReceiverFields());
             //in development
             //Debugger.Launch();
         }

Second was to improve the Nuget package description. I have added

<Version>2020.11.28.2108</Version>
    <Authors>Andrei Ignat</Authors>
    <PackageTags>RoslynCodeGenerators C# CSharp SkinnyControllers</PackageTags>
    <PackageProjectUrl>https://github.com/ignatandrei/AOP_With_Roslyn</PackageProjectUrl>
    <RepositoryUrl>https://github.com/ignatandrei/AOP_With_Roslyn</RepositoryUrl>
    <RepositoryType>GIT</RepositoryType>

     <PackageLicenseExpression>MIT</PackageLicenseExpression>
      <Copyright>MIT</Copyright>

Third was to improve documentation. I was adding a readme.txt.

<ItemGroup>
   <None Include=”../readme.txt”>
     <Pack>True</Pack>
     <PackagePath></PackagePath>
   </None>
</ItemGroup>

Fourth – automatic builds. You can see them at https://github.com/ignatandrei/AOP_With_Roslyn/actions
