Respect user's locale when rendering the date range in the repo activity page (#21410)

# Description
Previously, to make the date range understood by all, we used the format
"2006-01-02" for the dates as it's locale-generic.

This commit changes the rendering logic. Instead of rendering the date
on the server, we send a formatted computer-readable timestamp. The
client's javascript then renders it according to the user's locale.

This approach is reusable across the codebase, any `<time></time>` tag
with the data-format="date" attribute would get rendered according to
the user's chosen locale.

Inspiration:

I think either differentiating by class, or probably better by a custom
attribute such as `data-format` or similar, is the best course of
action.
