Added WakaTime Time-Based Badges to Shields.io

[ashif323]

Hi everyone

I recently contributed a new feature to Shields.io that adds time-based badges for WakaTime.

🔹 Supports:

1. /wakatime/user/{uuid}

2. /wakatime/project/{uuid}

🔹 Approach:
Since WakaTime doesn’t provide a JSON API for this data, I implemented SVG parsing to extract the required information.

All CI checks are passing and the PR is ready for review.

Would love feedback from the maintainers and community!
