- The code that gets contributor stats tried to store an
`map[string]*ContributorData` type in the cache, this works for the
memory cache but not for other caches such as Redis.
- The cache implementation for Redis would convert this map via
`fmt.Sprintf` to an string, which would simply print the pointer and not
the value of the pointer. Storing pointers is a no-go as this will get
GC-ed eventually within a few minutes. Therefore store everything with
json, that does properly store the value of the pointers.
- Adds unit test that verifies JSON is being used.
- Resolves https://codeberg.org/forgejo/forgejo/issues/3158
Continuation of https://github.com/go-gitea/gitea/pull/25439. Fixes #847

#### Overview
This is the implementation of a requested feature: Contributors graph
(#847)
It makes Activity page a multi-tab page and adds a new tab called
Contributors. Contributors tab shows the contribution graphs over time
since the repository existed. It also shows per user contribution graphs
for top 100 contributors. Top 100 is calculated based on the selected
contribution type (commits, additions or deletions).

#### Demo
(The demo is a bit old but still a good example to show off the main
features)

#### Features:
- Select contribution type (commits, additions or deletions)
- See overall and per user contribution graphs for the selected
contribution type
- Zoom and pan on graphs to see them in detail
- See top 100 contributors based on the selected contribution type and
selected time range
- Go directly to users' profile by clicking their name if they are
registered gitea users
- Cache the results so that when the same repository is visited again
fetching data will be faster
