feat: Clean up example5 and improve HTML script readability

Summary of changes
- Removed unnecessary blank line in page.mjs for clarity.
- Reformatted the script tag in test.html for better readability and maintainability.
- Corrected attribute name in generate.go to be consistent with its expected usage.

Changes
- In page.mjs, eliminated a blank line before the console.log statement, enhancing the structure of the code.
- In test.html, the script tag for page.mjs now has its attributes spread across multiple lines, making it easier to read and modify in the future.
- In generate.go, the attribute name was changed from "data-bob-alias" to "data-bob-aliases" to accurately reflect its purpose and maintain consistency in the data model across the application.
