[no-deprecated-functions] auto-detect error with monorepo-like project structure

Changing the auto detect from 
```ts
const jestPath = require.resolve('jest/package.json', {
      paths: [process.cwd()]
    });
```
to
```ts
const jestPath = require.resolve('jest/package.json', {
      paths: [process.cwd(), __dirname]
    });
```
fixes the bug introduced 15 months ago with non-root level projects.
