[To Avoid Misleading Information] Temporary add the last update date to the PancakeSwap Info

To avoid misleading information, temporary add the last update date to the PancakeSwap Info since it is not updated for more than two weeks

Currently, the page just states 'The data on this site has only synced to Binance Smart Chain block 4906616 (out of 5489996). Please check back soon.' We suggest to include the date, which is almost more than 2 weeks ago to avoid misleading information in the website
