[PR] Add predicate methods for previous and next day checks #37625

I added complimentarily predicate methods for time helpers.
This completes the today? predicate with its complementary helper methods tomorrow?, next_day?, yesterday? and prev_day?

Here is the PR for the same- https://github.com/rails/rails/pull/37625

Would appreciate if someone can review the PR and provide feedback :slight_smile:
