Changing the logo

We need to update the logo of the repository to align with our new branding guidelines. The current logo is outdated and does not reflect our updated visual identity. Improved clarity and modern design. Files to be updated Update README: Replace the old logo with the new one in the README.md file. Update Documentation: Ensure all documentation reflects the new logo. Other Locations: Update the logo on the project website, social media, and other relevant locations. Verify Consistency: Ensure that the new logo appears consistently across all materials.
