Fix Storybook Configuration for Windows Development Environment (#7904)

#### Description
This PR resolves issue #7903 regarding the Storybook configuration for
Windows development environments. Previously, the configuration script
generated forward slashes instead of backslashes, leading to errors when
running the command `npx nx run twenty-front:storybook:serve:dev
--configuration=modules` on Windows systems.

#### Changes Made
- Updated the Storybook configuration to ensure that backslashes are
used in file paths for Windows environments, preventing command
execution errors.

#### How to Test
1. **Run Storybook Command**:
   - On a Windows machine, execute the command:
     ```
     npx nx run twenty-front:storybook:serve:dev --configuration=modules
     ```
- Ensure that the command runs successfully without any path-related
errors.

2. **Verify Configuration**:
- Check the Storybook configuration files to confirm that paths are
using backslashes where applicable.
- Test the same command on non-Windows environments to verify that there
are no regressions.
