Make Basic example from the README runnable in CommonJS environment

[uglide]

The basic example in the README makes many assumptions about user environment and skills like a proper type field set in the closest package.json, or the user has copy-pasted the example to a file with .mjs extension.

In most cases, users will face the following problems:

• (node:59910) Warning: To load an ES module, set "type": "module" in the package.json or use the .mjs extension.
• SyntaxError: await is only valid in async functions and the top level bodies of modules
• No clear output is made, so it's hard to determine whether the example was executed successfully or not

Environment:

• Node.js Version: v19 or any
• Redis Server Version: Any
• Node Redis Version: Any
• Platform: Any
