anchor_movie_review_program::update_movie_review do not sanitize rating parameter

[T-Mathieu]

Problem

update_movie_review do not include any check on the rating input, allowing the rating to be out of the 1-5 limit.

This test highlights the situation:

it("Movie review is updated with incorrect rating`", async () => {
    const newDescription = "Wow this is new";
    const newRating = 10; // Rating should not be above 5
   
    const tx = await program.methods
      .updateMovieReview(movie.title, newDescription, newRating)
      .rpc();
   
    const account = await program.account.movieAccountState.fetch(moviePda);
    expect(newRating === account.rating);
    expect(newDescription === account.description);
  });

Proposed Solution

Add the same require! in update_movie_review as in add_movie_review:

require!(rating >= MIN_RATING && rating <= MAX_RATING, MovieReviewError::InvalidRating);
