add TooManyCommentsViolation

# Rule request <!-- Thanks for coming up with a proposal! --> ## Thesis <!-- What exactly do you propose? Please, provide code examples. --> Nowadays, developers often use an excessive number of comments, which leads to unclear code, loss of readability, increased cognitive load, trying replace good documentation. This rule complements [WPS 402.](https://wemake-python-styleguide.readthedocs.io/en/latest/pages/usage/violations/best_practices.html#wemake_python_styleguide.violations.best_practices.OveruseOfNoqaCommentViolation). Let's be honest: people often write comments because their code is less readable and overly complex. ## Reasoning The most appropriate solution is to introduce a new violation called `TooManyCommentsViolation`. This violation would enforce a maximum of `N` comments inside functions or methods (and in the future, we could extend it to all files). <!-- Why do you think this is a good idea? Please, include some strong points and considerations. --> <!-- Love wemake-python-styleguide? ❤️ Do you want your features to be implemented faster?
