Before this patch, we were using `Date` getter/setter methods that
worked with local time to get a list of Sundays that are in the range of
some start date and end date. The problem with this was that the Sundays
are in Unix epoch time and when we changed the "startDate" argument that
was passed to make sure it is on a Sunday, this change would be
reflected when we convert it to Unix epoch time. More specifically, I
observed that we may get different Unix epochs depending on your
timezone when the returned list should rather be timezone-agnostic.
This led to issues in US timezones that caused the contributor, code
frequency, and recent commit charts to not show any chart data. This fix
resolves this by using getter/setter methods that work with UTC since it
isn't dependent on timezones.
Fixes#30851.

#### 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
