singleCellSignalsPeaks.html: reword two dataset descriptions

Recast two dangling participial phrases ("...describing about 1.2 million
elements", "...defining 359,022 elements") as plain clauses.

 This track collects the cell-type chromatin accessibility tracks from the
 single-cell ATAC-seq datasets in the
 <a href="https://cells.ucsc.edu" target="_blank">UCSC Cell Browser</a>. For each
 dataset it shows the read-coverage signal (bigWig) and, where the study
 reported them, the accessible-region peak calls (bigBed and narrowPeak), split
 out by cell type. The datasets cover several human tissues, including brain,
 heart, and retina.

 <p>
 The subtracks come from these datasets:
