Paths supplied by the host editor should be normalized

[SeeminglyScience]

Different editors can supply paths slightly differently, we should make sure we normalize it before storing in a public API. For example, here's $psEditor.Workspace in VSCode and Atom

# VSCode
$psEditor.Workspace

# Path
# ----
# c:\Projects\PowerShellEditorServices

# Atom
$psEditor.Workspace

# Path                                                           
# ----                                                           
# C:\Projects\PowerShellEditorServices\

I wonder what Linux and macOS does in this scenario. 🤔
