Checklist

• Added a function "binary_cross_entropy"
• Added test function "test_paddle_binary_cross_entropy"
• Followed all steps provided

The tests encountered an issue "Frontend function returned non-frontend arrays: ivy.array([float, float])". I think this happens because the ground-truth function returns a paddle.Tensor object while this function returns an ivy.frontends.paddle.Tensor object. In converting the ivy array to a paddle tensor I used ivy.functional.frontends.paddle.to_tensor() which does not return the same data type as paddle.to_tensor().

Thanks for contributing to Ivy! 😊👏
Here are some of the important points from our Contributing Guidelines 📝:
1. Feel free to ignore the run_tests (1), run_tests (2), … jobs, and only look at the display_test_results job. 👀 It contains the following two sections:
- Combined Test Results: This shows the results of all the ivy tests that ran on the PR. ✔️
- New Failures Introduced: This lists the tests that are passing on main, but fail on the PR Fork. Please try to make sure that there are no such tests. 💪
2. The lint / Check formatting / check-formatting tests check for the formatting of your code. 📜 If it fails, please check the exact error message in the logs and fix the same. ⚠️🔧
3. Finally, the test-docstrings / run-docstring-tests check for the changes made in docstrings of the functions. This may be skipped, as well. 📚
Happy coding! 🎉👨‍💻
