Minor changes

[drona-gyawali]

While working and studying on the project, I noticed a couple of things that could be improved:

1. There are some unnecessary print statements in the test cases. I believe these should be removed as they might cause confusion for new contributors and are not considered a good practice.

2. The README contains a broken link to the contribution guide. The current link:
   https://github.com/certego/BuffaLogs/blob/develop/docs/CONTRIBUTING.md
   should be updated to:
   https://github.com/certego/BuffaLogs/blob/develop/CONTRIBUTING.md.
   

Before proceeding with a PR, I’d like to confirm if these fixes align with the project's guidelines. Please let me know your thoughts. Thank you.

Hi @drona-gyawali, regaring the first point, I opened an issue: #176

Since the CONTRIBUTING file it's really important, I'll fix the link immediately, but thank you very much for your advise
