vscode live share settings

By default while using vscode live share it is hard to work on
skins and extensions of mediawiki using the core repo as a project
base, as extensions and skins are included in .gitignore files.

Configuration of the sharing behaviour is possible and documented at
https://docs.microsoft.com/en-us/visualstudio/liveshare/reference/security

The files added in this commit mean that by default:
 - .gitignore files are treated in the default way for the system
   meaning they are hidden, but accessible.
 - core node_modules and vendor and shared and in the tree
 - extensions and skins are shared and in the tree
