The authors regret that, in the original article, the green curves in the right panels of Figs. S1 and S2 and Videos 1 and 2 appeared slightly higher than they should have. The corrected figures appear here, and the figure and video legends remain unchanged. The conclusions of the paper are not affected by these errors, and all discussion of the data presented is still correct. The errors appear in print and in PDFs downloaded before June 18, 2024.
