@fdodino probando lo de buscar el package.json en el CI me di cuenta que no estaba funcando para Windows (o sea que siempre estaba tomando todo el path desde el origen).

Hacer la tranformación de algo que llega en el LSP como

file:///d%3A/a/wollok-lsp-ide/wollok-lsp-ide/client/testFixture/pepitaGame/juego

a algo como lo que espera el fs

D:\a\wollok-lsp-ide\wollok-lsp-ide\client\testFixture\pepitaGame\juego

No era muy trivial, así que opté por volver al plan original de hacerlo en base al workspace folder. Te aviso por si querés revisarlo otra vez, porque cambió bastante la implementación (básicamente ya no se usa la función que busca el package.json pa'rriba).
