Description
### Have you read the Contributing Guidelines on issues?
- [X] I have read the [Contributing Guidelines on issues](https://github.com/facebook/docusaurus/blob/main/CONTRIBUTING.md#issues).
### Prerequisites
- [X] I'm using the latest version of Docusaurus.
- [X] I have tried the `npm run clear` or `yarn clear` command.
- [X] I have tried `rm -rf node_modules yarn.lock package-lock.json` and re-installing packages.
- [X] I have tried creating a repro with https://new.docusaurus.io.
- [X] I have read the console error message carefully (if applicable).
### Description
The code to print console error messages is quite bad:
```tsx
import formatWebpackMessages from 'react-dev-utils/formatWebpackMessages';
export function formatStatsErrorMessage(
statsJson: ReturnType | undefined,
): string | undefined {
if (statsJson?.errors?.length) {
const {errors} = formatWebpackMessages(statsJson);
return errors
.map((str) => logger.red(str))
.join(`\n\n${logger.yellow('--------------------------')}\n\n`);
}
return undefined;
}
```
`'react-dev-utils/formatWebpackMessages'` does not print all the relevant info, notably the file path that on which the error happens, and this prevents users from solving their problems.

### Reproducible demo
_No response_
### Steps to reproduce
- init new site
- add `src/thing.xyz`
- add `import './thing.xyz'` on `src/index.tsx`
Console error:
However, the Dev Server error overlay works better:
### Expected behavior
We should print relevant information to the console. At least the file path.
This info is definitively available in the Webpack stats:
```js
const stats = {
errors: [
{
moduleIdentifier: '/Users/sebastienlorber/Desktop/website/src/pages/thing.xyz',
moduleName: './src/pages/thing.xyz',
loc: '1:0',
message: "Module parse failed: Unexpected character '🔥' (1:0)\n" +
'You may need an appropriate loader to handle this file type, currently no loaders are configured to process this file. See https://webpack.js.org/concepts#loaders\n' +
'> 🔥 bad file content'
}
],
errorsCount: 1,
warnings: [],
warningsCount: 0
}
```
### Actual behavior
Error message does not contain the problematic file path
### Your environment
- Docusaurus version used: v2.4.1 or v3 canary
### Self-service
- [X] I'd be willing to fix this bug myself.
