Add new Chromium based and Edge Nightly to compat table

[AndreasGalster]

Edge is switching to Chromium, there are already preview builds out, it's likely the new Chromium based browser will be out of beta around the October Windows release.

In line with this Microsoft also created new "channels" similar to Chrome & Firefox has it, see here: https://www.microsoftedgeinsider.com/en-us/download/

There are nightly builds for Edge based on Chromium, so I think it would make sense to consider adding this to the table.

We have Edge and Edge Beta in table now. Dev and Canary are the only missing parts
