SA1009 can trigger when a closing parenthesis ends XML comment's cref attribute

[peteroupc]

SA1009 can trigger (and output the message "Closing parenthesis should be followed by a space") when a closing parenthesis ends a cref attribute in XML documentation, as in the following example:

/// <summary>This is a test.  
/// <see cref='MyClass.MyMethod(System.String)'/></summary>

In general, SA1009 should not apply to closing parentheses in comments at all.

This started occurring with #1840. The bug occurs for the specific case of single quoted XML attributes.

📝 The analysis of parentheses in cref attributes is intentional, as mentioned in #1834 (comment).
