C# generated code does not include public XML comments or disable 1591

Godot version

4.0.0-beta1

System information

macOS 12

Issue description

Running dotnet build in C# Projects which have <GenerateDocumentationFile>true</GenerateDocumentationFile> specified in their *.csproj files results in warnings from the code produced by the Godot dotnet source generators:

warning CS1591: Missing XML comment for publicly visible type or member 'Main.SignalName'
warning CS1591: Missing XML comment for publicly visible type or member 'Main.RestoreGodotObjectData(GodotSerializationInfo)'
...etc

I currently maintain 5 packages for Godot whose public API's are fully documented and require GenerateDocumentationFile on those packages.

Possible solution:

The Godot source generators are already emitting #pragma warning disable for other rules (here's one such example).

Since Microsoft doesn't seem to care, I believe we should add a #pragma warning disable 1591 to every new or modified API added by the Godot dotnet source generators.

Steps to reproduce

Essentially, any project which contains <GenerateDocumentationFile>true</GenerateDocumentationFile> in the *.csproj file will result in build warnings about missing documentation from the Godot dotnet source generator output.

Minimal reproduction project

I am working on updating one of my smallest packages to Godot 4. You can reference the godot4 branch of go_dot_collections here as a minimum reproduction sample: https://github.com/chickensoft-games/go_dot_collections/tree/godot4

I will add to this rather than submitting a new issue, this causes any C# project to be unable to build if "Treat warnings as errors" is enabled in the csproj (TreatWarningsAsErrors>True</TreatWarningsAsErrors>), making the setting functionally unusable for Godot projects.
