Implement code frequency graph (#29191)
### Overview This is the implementation of Code Frequency page. This feature was mentioned on these issues: #18262, #7392. It adds another tab to Activity page called Code Frequency. Code Frequency tab shows additions and deletions over time since the repository existed. Before: <img width="1296" alt="image" src="https://github.com/go-gitea/gitea/assets/32161460/2603504f-aee7-4929-a8c4-fb3412a7a0f6"> After: <img width="1296" alt="image" src="https://github.com/go-gitea/gitea/assets/32161460/58c03721-729f-4536-a663-9f337f240963"> --- #### Features - See additions deletions over time since repository existed - Click on "Additions" or "Deletions" legend to show only one type of contribution - Use the same cache from Contributors page so that the loading of data will be fast once it is cached by visiting either one of the pages --------- Co-authored-by: Giteabot <teabot@gitea.io>
