Add LICENSE file and fix README text inconsistencies #129

Description

The README.md states that the project is licensed under the MIT License, but there is currently no LICENSE file in the repository's root directory. Additionally, there is a minor text inconsistency in the Contributors section.

Proposed Changes

• Add LICENSE File: Create a formal LICENSE file (MIT) in the root directory to ensure the project is legally compliant for open-source contributions.
• Fix Project Name Inconsistency: In the "Our Contributors" section, the text currently references "Ratna-Supermarket." This should be updated to "BlogLog" to match the actual project.
  Current Text: "...elevating Ratna-Supermarket to greater heights."
  Suggested Correction: "...elevating BlogLog to greater heights."
