Automatic fix for RS0016 removes exetension methods declared using new syntax.

The automatic fix for RS0016 keeps removing the public API for the .NET 10 style extension members.

e.g.

    /// <summary>Extensions for vectors with elements implementing <see cref="IRootFunctions{TSelf}"/>.</summary>
    extension<T>(Vector2D<T> vector)
        where T : IRootFunctions<T>
    {
        /// <summary>Gets the length of the vector.</summary>
        public T Length => T.Sqrt(vector.LengthSquared);
    }

    /// <summary>Extensions for vectors with elements implementing <see cref="INumberBase{TSelf}"/>.</summary>
    extension<T>(Vector2D<T> vector)
        where T : INumberBase<T>
    {
        /// <summary>Gets the length squared of the vector.</summary>
        public T LengthSquared => Vector2D.Dot(vector, vector);
    }

This is a pretty big problem when evolving an API to use the new syntax because the analyzer can get into a bi-stable state where it will not fully add all of the APIs. It will remove some and add some, but never converge.

Only through manual editing of the (perhaps daunting) PublicAPI.*.txt with the use of a 3-way merge tool can it be properly staged. Once in the correct state, there is no problem. But getting there requires outside tools or self-flagellation.

It may be dropping all properties when adding methods or something like that.
