Add config for vscode-jest extension

Summary:
Provides a much nicer devx, shows test pass / failure in the editor and error messages in line

https://pxl.cl/25G0x

When the extension is installed with this config it will watch all test and run what is needed, automatically updating the editor with test status

It also supports debugging tests individually right in the editor

see https://github.com/jest-community/vscode-jest for full docs

Also Once VS code @ fb is updated to a newer base of vscode, we will get access to to the testing sidebar feature
