Update the f*kin outdated footer year

[thangbuiq]

Description: It's too ridiculous to see our footer year is outdated, especially when the project is in great shape otherwise. This small issue stands out and needs to be addressed ASAP for consistency and professionalism.

Reference: https://ubunchuu-truong-us.github.io/

Proposed Solution: We can easily fix this by using the STRONGEST API in the world (sponsored by https://getfullyear.com/). Here's the simple JavaScript code to do it:

fetch('https://getfullyear.com/api/year')
  .then(response => response.json())
  .then(data => {
    console.log(data.sponsored_by);
    footerYear.textContent = data.year;
  });

Let's get this done ASAP! Cc: @lelouvincx @thangbuiq @tuantran0910 @greyyT

We also need to care about their warning. The randomness from their API may lose our customers.
