Small typos in anchor-cpi.md leading to failing tests

Problem

Found these small typos while I was going through this lesson. One of the typos in the code snippets was leading to failing tests when running anchor test at the end of the lab:

  anchor-movie-review-program
    ✔ Initializes the reward token (271ms)
    1) Movie review is added
    2) Movie review is updated
    3) Movie review is deleted


  1 passing (305ms)
  3 failing

  1) anchor-movie-review-program
       Movie review is added:
     Simulation failed. 
Message: Transaction simulation failed: Error processing Instruction 0: custom program error: 0x4. 
Logs: 
[
  "Program log: Title: Test Movie",
  "Program log: Description: This was a very good movie.",
  "Program log: Rating: 5",

  "Program log: Instruction: MintTo",
  "Program log: Error: owner does not match",

]. 
Catch the `SendTransactionError` and call `getLogs()` on it for full details.
  

  2) anchor-movie-review-program
       Movie review is updated:
     Error: AnchorError caused by account: movie_review. Error Code: AccountNotInitialized. Error Number: 3012. Error Message: The program expected this account to be already initialized.

      at processTicksAndRejections (node:internal/process/task_queues:105:5)

  3) anchor-movie-review-program
       Movie review is deleted:
     Error: AnchorError caused by account: movie_review. Error Code: AccountNotInitialized. Error Number: 3012. Error Message: The program expected this account to be already initialized.

      at processTicksAndRejections (node:internal/process/task_queues:105:5)



error Command failed with exit code 3.
