Code Navigation issue when using PNPM workspaces

## Actual Behavior

Hi. I have my project setup as a [PNPM workspace](https://pnpm.js.org/en/workspaces) and VSCode GraphQL has been working well except for 1 issue - It navigates within `node_modules` folder where PNPM has symlinked the file (as part of PNPM workspaces) instead of the actual file itself. I am adding a gif below demonstrating the same:


If you notice, the real fragment file is within `sdk/fragments` but it gooes inside `node_modules` and gets the same file from the symlinked `node_modules` folder.

## Expected Behavior

Code navigation navigates to the real graphql file instead.
