🐛 Bug Report

I cannot find the way to use addConditionalFormatting() method on a Worksheet in TypeScript.

Lib version: 3.8.1

Steps To Reproduce

constwb=awaitworkbook.xlsx.readFile(`./template.xlsx`);constmySheet:Worksheet=wb.getWorksheet(1);mySheet.addConditionalFormatting({})// error TS2339: Property 'addConditionalFormatting' does not exist on type 'Worksheet'.

The expected behaviour:

Since it is supported in JS would be nice to have it in TS as well.
