A. You have a typo in the name of this variable:

const startingTimeStampe = await raffle.getLastTimeStamp();

It should be startingTimeStamp

B. In hardhat.config.js file make the mocha section look like this:

mocha: {
    timeout: 500000,
  },

Using setTimeout like you currently have it is not giving enough time for the Promise to be resolved.

That section is working, is sending the prize to you

In etherscan:

I can see that you have entered the Raffle 2 times by paying the entrance fee of 0.01 ETH.

Now, if we check the internal transactions tab in the contract address:

You will see two set of transactions with 4 transactions each. These transaction are performUpKeep and fullFillRandomWords not call by your contract but by Chainlink nodes after picking the events.

You will see that two transactions have a value of 0.01 ETH, those transactions are the fullFillRandomWords from your contract called by a node and sending the prize to you.

To finish:

If you check the internal transactions tabs of your wallet address, you will see the 0.01 ETH send to you after winning the Raffle. I have noticed that withdrawing funds from contracts are registered as internal transactions.
