**Backport:** https://codeberg.org/forgejo/forgejo/pulls/8882
The repository contributors graph received the stats for each author for each week, these weeks are stored as unix milis values, `Object.entries` converted these values to strings and `sort()` would thus sort them as strings - this worked without a problem for most repository.
If a repository has commits from before 'Sun Sep 9 03:46:40 AM CEST 2001', it meant that the weeks when those commits were made would be sorted towards the end because "1000000000" > "999999999" (when compared as strings) and would thus be silently cut from the data. This edge-case was seen by the curl repository (https://mastodon.social/@bagder/115018271785548165)
Sort them as numbers to avoid this problem, it being stored as strings is otherwise not a problem.
