[prudhvigodithi]

Is your feature request related to a problem?

Coming from central release dashboard #51, have a visualization in central release dashboard to able to see the Release branch code coverage scores.

What solution would you like?

• Use the code coverage API.
• Filter per repo and branch.
• Take the completed run from the latest head commit.
• Get the Code coverage score.

Example https://api.codecov.io/api/v2/github/opensearch-project/repos/index-management/commits?branch=main

Do you have any additional context?

• Some of the repos the code coverage timestamp is older even while the repo is active.
• The coverage shown is for the older commit even though the head commit is different.
