Narrow down Edge version in browser support docs (#11640)

* Narrow down Edge version in browser support docs

I noticed that Edge 14 has a pretty buggy fetch implementation and
because it has already reached end of support I think it's better we
don't specifically state support for it, even if it may work to some
extend.

* mention both edge versions
