Display all the contributions for each person in a project that has 2 or more repos

### Overview
We need to change the code for displaying the contribution data so that it can display all the contributions for each person in a project that has 2 or more repositories (repos). This contributions data is used for the _All-Time Contributors_ section of each project's detailed page.

### Action Items
- [ ] Understand how the current code figures out the number of contributions for each contributor in a project.
- [ ] See the following as a starting point: [^1][^2][^3].
- [ ] Since you will need to use the info in the `identification` field and `additional-repo-ids` field of each project's Markdown file in the `_projects` directory [^insert number here], you may want to see how the languages from multiple repos were combined as seen in #5160.

### Resources/Instructions
- This issue is tracked in #6138
[^1]: Note: The Civic Tech Index (CTI) repos have combined contributors because the current code adds up the contributions for each person in the `civictechindex` GitHub organization and uses that for the contributions for the CTI project. The current code only does this for projects outside the `hackforla` GitHub organization.

[^3]: ADD ADDITIONAL RESOURCES TO HELP UNDERSTANDING OF HOW CONTRIBUTORS WORK
