Can't find `.prettierrc` file when formatting `settings.json` on Windows.

### Summary

Formatting the user `settings.json` on Windows with Prettier does not detect the `.prettierrc.json` file correctly. If there are overrides specified in the `.prettierrc.json` file located in the home directory, Prettier ignores all settings specified in the override except for `parser`.

### Github Repository to Reproduce Issue

As the two files in question need to be placed in specific locations on the system, I have opted to include them as text below.

<details>
<summary>Sample <code>.prettierrc.json</code></summary>

```json
{
    "tabWidth": 4,
    "overrides": [
        {
            "files": [
                "foo.json",
                "**/.vscode/*.json",
                "**/tsconfig.json",
                "**/tsconfig.*.json",
                "**/AppData/Roaming/Code/User/*.json"
            ],
            "options": {
                "tabWidth": 4,
                "parser": "json5",
                "quoteProps": "preserve",
                "singleQuote": false,
                "trailingComma": "all"
            }
        }
    ]
}
```
</details>

<details>
<summary>Sample <code>settings.json</code></summary>

```json
{
    "markdownlint.config": {
        "MD007": {
            "indent": 4,
        },
        "MD024": false,
        "MD033": {
            "allowed_elements": ["kbd", "br", "details", "summary"]
        }
    }
}
```
</details>

### Steps To Reproduce:

1.  Save `.prettierrc.json` noted above to `C:\Users\[username]\.prettierrc.json`
1.  Open VS Code user `settings.json` (Located in `C:\Users\[username]\AppData\Roaming\Code\User\settings.json`)
1.  Run **Format Document** with Prettier.

### Expected result

The sample `settings.json` should be formatted as follows:

```json
{
    "markdownlint.config": {
        "MD007": {
            "indent": 4,
        },
        "MD024": false,
        "MD033": {
            "allowed_elements": ["kbd", "br", "details", "summary"],
        },
    },
}
```

### Actual result

Actual `settings.json`:

```json
{
    "markdownlint.config": {
        MD007: {
            "indent": 4,
        },
        MD024: false,
        MD033: {
            allowed_elements: ["kbd", "br", "details", "summary"],
        },
    },
}
```

### Additional information

Looking through the logs, it initially appears that the `.prettierrc.json` is not recognized when formatting the user `settings.json` file, however, that is not entirely the case.
The `parser` property is overriden by the `.prettierrc.json`, other properties, such as `quoteProps` and `trailingComma` are not recognized.

I have tried the formatting test under various conditions. Here are the logs for some things I tried that formatted as expected.

Note that `json5` is not the default parser used for the `settings.json` file; Prettier is getting that from the `.prettierrc.json` file.
