App 122 deprecation message

[schloerke]

`shiny::renderDataTable()` is deprecated as of shiny 1.8.1.
Please use `DT::renderDT()` instead.
Since you have a suitable version of DT (>= v0.32.1), shiny::renderDataTable() will automatically use DT::renderDT() under-the-hood.
If this happens to break your app, set `options(shiny.legacy.datatable = TRUE)` to get the legacy datatable implementation (or `FALSE` to squelch this message).
