Update simple-game to be the version of using fiber-sdk

[ashuralyk]

There soon would be an official fiber-sdk to ship fiber development simplicity to the public, so for the best exploration of it, it's good to apply demo changes directly on fiber-docs here.

note: some file changes are from code formatter.

A member of the Team first needs to authorize it.

Thanks for the PR! The SDK integration looks great and will definitely make it easier for developers to get started with Fiber. I have a couple of suggestions:

1. Could you update the repository links to point to https://github.com/nervosnetwork/fiber-docs/tree/master/example/simple-game instead of the personal repo? Keeping the example under the official organization repo would help with long-term maintenance and make it easier for users to find and trust the code.. You may also need to update the code under the example directory accordingly.

2. Would you mind separating the code formatting changes into a separate commit? It would make the review process much easier if the functional changes (SDK integration) and the style/formatting changes were in distinct commits.

Let me know what you think!

Following the documentation, several issues arose:

The repository link shifted from the official repository to a personal repository, which is detrimental to long-term maintenance. --repeat issue

The code in the simple-game directory was not updated synchronously. The PR only modified the documentation, but the actual code in the local simple-game directory remains the old version. If users clone the official repository's simple-game as per the documentation, the code is completely incompatible with the documentation.

The newInvoice function lacks the finalExpiryDelta parameter. According to the documentation example from @ckb-ccc/fiber on npm, the finalExpiryDelta parameter is required:
sdk.newInvoice({ amount, currency, paymentPreimage, description, expiry, finalExpiryDelta: "0x9283C0", // <-- The code in the PR didn't include this
})

The return value structure of listChannels has changed. The SDK version of listChannels directly returns a Channel[] array, while the old version returns a { channels: Channel[] } wrapper object. The code in the PR documentation correctly accommodates this, but simple-game hasn't changed it.

The peerID has been hardcoded to change, and this part hasn't been updated in sync with the peerID in the example code block (the documentation still shows the old peerID as an example).
