Add Quickwit trend page

Adds quickwit-oss/quickwit as a third tracked repo with the standard
chart set (no integration charts — quickwit doesn't use
source:/transform:/sink: label prefixes, so plot_integration_trends and
plot_label_state_counts correctly skip). README gets a third bullet
under Trends.
