Add more details to quantify contribution for each member

Is your feature request related to a problem? Please describe.
We can only know the total number of PRs and issues created by the member but no specific details.

Describe the solution you'd like
Split the total count into "issues created", "number of PR made" and ("number of PR reviewed" vs "number of PR review comments") and display multiple numbers beside the user profile photo. The meaning of the number will be displayed when we have the mouse hovering over the number.

Describe alternatives you've considered
While also having splitter count, we may have icons to indicate the meaning of the number. -- But I am unsure about what the icons should look like.

Additional context
I think number of PR reviewed and number of PR comments made are good but similar metrics to measure a member's contribution on reviewing PR and keeping one of them should be sufficient. However, I am unsure about the best way to present the data.

This is a good thought, but I am unsure if it will cause the tables headers to look too cluttered.

number of PR comments each user makes

This is actually more of a Activity Dashboard feature than a Issue Dashboard feature. If I'm not wrong, additional github calls must be made to retrieve those.

We can only know the total number of PRs and issues created by the member but no specific details.

There is a way to check each member's PR and issue count, by filtering by Type. The total number then reflects each member's PR count/ issue count depending on the filter.

I think it would be better implemented as a hover, hover over the total count to get the breakdown of issues and PRs. Up for discussion
