Fixed close tab and close window shortcut

[FastestMolasses]

Description

The command + w shortcut closes the editor instead of the current file. The functionality to close the current file was already implemented in CodeEdit/Features/Tabs/Views/TabBarItemView.swift. The fix was to remove this shortcut from CodeEdit/Features/WindowCommands/FileCommands.swift where it explicitly closes the editor. I moved this code to the correct keyboard shortcut (⌃⇧⌘W) which is the same as the one in Xcode.

Looking back at this, the change I made by removing the shortcut from CodeEdit/Features/WindowCommands/FileCommands.swift means that it won't close the editor window when there are no open files. If instead you would like the editor to close when pressing "command + w" when theres no opened files, I can add this piece back in.

I would prefer that cmd+w just closes the tabs. if there are no active tabs open, i press cmd+q to close the app.

others might disagree tho
