Following publication of the original article (Li et al. 2022), the author noticed the errors in the figures. In the published version, Figs. 6 and 7A are misused. The author has wrongly uploaded these figures in the manuscript package which have been processed by the typesetter. However, the text citations and captions of these figures seem to be correct. The corrected Figs. 6 and 7A have been published in this correction.
