Leetcode: hide testcase από Ashmit Jagtap

This extension helps hide the failed testcase while practicing on Leetcode.
This is quite a simple extension that just hides the testcases you fail on leetcode while practicing.
To be able to view the test cases again, you can simply disable the extension and reload.

Now practitioners can better their trouble shooting skills and no more guilty indulgence in test cases ;)
