[Fix] GitHub Caching rendering outdated SVGs

Issue(s)

Acceptance Criteria fulfillment

• [x] Updated the served widgets headers to avoid GitHub caching outdated SVGs. Adding a updated url so that GitHub can render and update the widget based on the updated headers.

Proposed changes (including videos or screenshots)

• The current caching mechanism by our CDN which was serving the contributor metrics widget did not provide a Cache-Control : max-age header value to GitHub. This lead to GitHub caching the widget svg forever, leading to old data.
• We have updated the headers and set max-age to two hours.
• Updated the url to render updated widget.
