python-jupyterlab does not know how to open browser

[Kreijstal]

Description / Steps to reproduce the issue

Jupyter nor jupyterlab can't open browser, the reason is the path transformation is wrong they try to open "file:///C://" which windows does not find. However "file://C:/" will work, a workaround is to do path replacement like this

jupyter lab --browser "powershell start ('\"%s\"' -replace '\"//\"','\"/\"')"

Expected behavior

jupyter lab opens browser

Actual behavior

jupyter lab does not open browser like in every other distro
