Describe the bug

@graphql-tools/git-loader can't find graphql definitions if they are in the upper directory.
This might be because git ls-tree can't search upper directory by default.

To Reproduce
Steps to reproduce the behavior:

1. Create a monorepo like project structure.

├── .git
├── schemas
│   └── sample.graphql
└── packages
    └── graphql-loader
        └── index.js
        └── package.json

2. Move to packages/graphql-loader dir.
3. Run packages/graphql-loader/index.js. The code is like below.

import { loadSchema } from '@graphql-tools/load';
import { GitLoader } from '@graphql-tools/git-loader';

(async () => {
  const schema = await loadSchema('git:origin/master:./schemas/**/*.graphql', {
    loaders: [new GitLoader()],
  });
  console.log(schema);
})();

4. Step 3 will throw Error: Unable to find any GraphQL type definitions for the following pointers:.
5. Even if we pass cwd option to loadSchema, it will fail.

Expected behavior

Can load graphql definitions.

Environment:

• OS: macOS
• @graphql-tools/git-loader: 7.2.20
• @graphql-tools/load: 7.8.12
• NodeJS: 19.7.0
