Upgrade web-vitals library to V5

Problem Statement

Hello! 👋

We noticed some of our LCP metrics are reported without elements and the potential fix to this issue might be already included in the version 5 of web-vitals.

For more details: GoogleChrome/web-vitals#561

Solution Brainstorm

We propose to upgrade web-vitails to v5 to see if that could fix it
