Lybunt report - remove broken chart functionality
I'd like to propose removing the broken chart functionality from the lybunt report
There is a general level of brokenness with Charts in Civi (Luciano has a promising replacement option here https://lab.civicrm.org/partners/ixiam/reportplus/blob/2.x/CRM/Reportplus/Utils/ChartJS.php#L8)
But for Lybunt it appears to be specifically & extra broken & this appears to be non-recent.
I propose that we remove the support for charts from this report. I've had a look & I can see nothing about the existing code that would make it easier to get the charts working again at some later point if we went that way (although I suspect we should be looking at something more robust that this report if we want to put that effort in)
