Record-syntax issues

[TobiasWolters]

Consider the following case, using the new record-syntax from C# 9.0:

public class A
{
    /// <summary>
    ///     Int comment
    /// </summary>
    public int Int { get; set; }
}

/// <summary>
///     B documentation
/// </summary>
/// <param name="Int"><inheritdoc cref="A.Int"/></param>
public record B(int Int);

With the current version (1.3.0) of InheritDoc, this results in the following warnings and does not follow the inheritdoc:

• warning CS1574: XML comment has cref attribute 'Int' that could not be resolved
• InheritDocTask warning IDT002: No matching documentation could be found for: T:InheritDocTest.B, which attempts to inherit from: !:A.Int
• No matching documentation could be found for: M:InheritDocTest.B.#ctor(System.Int32), which attempts to inherit from: !:A.Int

Ideally, InheritDoc should be able to resolve the inheritdoc to 'Int comment' without any warnings.
