Detekt should detect multiple line ?. operator for nullable items to be merged into one

[tusharaina]

Expected Behavior of the rule

dialog?.let { 
            it.window?.let { 
                //do something with window
            }
        }

Here both dialog and window are nullable. So detekt should give error/warning to merge these two into one statement. Currently detekt does not detect this and we could add new rule to detect this behaviour to merge these two into one statement like below:

dialog?.window?.let { 
                //do something with window
            }
        }

Context

This would improve code readability as well as maintainability.

Closing in favor of #6373. I agree that this should be flagged by detekt but it should be handled by UnnecessaryLet.
