Add vscode projects plugin as a submodule

[Sharsie]

Following in the steps of @mqus , this PR will add Visual Studio Code autosuggestion support as a submodule to albert launcher python plugins.

Since I was meddling with the jetbrains plugin in the past, I took the liberty to make something similar for VS Code.

Supports

• autosuggestions for recently opened paths as seen in the VS Code menu dialog - builds on top of the more verbose menu entries
• Projects managed by Project Manager plugin
