Typo in HubConnectionExtensions xml docs

[ErisApps]

Is there an existing issue for this?

• I have searched the existing issues

Describe the bug

HubConnectionExtensions partial classes xml docs reference itself

/// <summary>
/// Extension methods for <see cref="HubConnectionExtensions"/>.
/// </summary>
public static partial class HubConnectionExtensions
{
    ...
}

Expected Behavior

HubConnectionExtensions partial classes xml docs should reference HubConnection instead.

/// <summary>
/// Extension methods for <see cref="HubConnection"/>.
/// </summary>
public static partial class HubConnectionExtensions
{
    ...
}
