Yarn Plug n Play support

[lewisloofis]

Hello,

Does this langserver has a plan to support Yarn pnp. This langserver will report cannot find module errors if I happen to use yarn pnp feature.

There are several attempt to patch tsc using pnpify, this is the docs about it.

Would be great if this langserver support pnp, cause I don't need to leave my vim cause of wrong syntax checking
