Issue: [Bug]: Storybook prefixing stories path './' causing not found module for stories files
Labels: bug,question / support,builder-webpack5

### Describe the bug

I added v8.1.1 of @Storybook/react and the portal came-up and I see my stories listed in components panel but they are not loading and throwing error
`Error: Cannot find module './src/cont/exam.stories.js'
    at webpackEmptyContext (http://localhost:xxxx/main.iframe.bundle.js:211:10)
    at http://localhost:xxxx/main.iframe.bundle.js:189:312`

This is my project structure

project/
├── .storybook/
│   └── main.js
├── src/
│   └── cont/
│       └── exam.stories.js

This is my main.js in .storybook folder

```
import * as path from "path";

const {resolve} = require("path");
/** @type { import('@storybook/react-webpack5').StorybookConfig } */
const config = {
  stories: ['../src/**/*.stories.js'], //'../src/**/*.stories.js']
  addons: [
    "@storybook/addon-onboarding",
    "@storybook/addon-links",
    "@storybook/addon-essentials",
    "@chromatic-com/storybook",
    "@storybook/addon-interactions",
  ],
  framework: {
    name: "@storybook/react-webpack5",
    options: {},
  },
  webpackFinal: async (config, { configType }) => {
    console.log('Current working directory:', process.cwd());
    console.log('Current working __dirname:', __dirname);
    console.log('Resolved alias @:', path.resolve(__dirname, '../src'));

    config.module.rules = config.module.rules.filter(rule => {
      if (rule.test && rule.test.toString().includes('js|mjs|jsx|ts|tsx')) {
        return false;
      }
      return true;
    });

    // Add swc-loader for JavaScript files
    config.module.rules.push({
      test: /\.(js|mjs|jsx)$/,
      exclude: /node_modules/,
      use: {
        loader: 'swc-loader',
        options: {
          jsc: {
            parser: {
              syntax: 'ecmascript',
              jsx: true,
              decorators: true
            },
            transform: {
              legacyDecorator: true,
              decoratorMetadata: true,
              react: {
                runtime: 'automatic'
              }
            }
          }
        }
      }
    });

    return config;
  },
};
export default config;
```
Also why is Storybook adding './' for any path specified for stories

thanks in advance for the help!
