gqty --watch not watching schema files in parent directory

[lubosmato]

Steps to reproduce:

1. Put schema.graphql in a parent directory
2. Run gqty --react --no-subscriptions --target=./generated/gqty.ts --typescript --watch ../schema.graphql
3. Change schema.graphql
4. Observe gqty didn't pick up the change of schema.graphql

Typical use-case for watching schema files from parent directories is e.g. in turborepo project where api and frontend are in separate folders and schema file is in api folder.
