Remove unused dependencies from DESCRIPTION

Drop clusterProfiler and org.Sc.sgd.db from Suggests (GSEA vignette
section replaced with descriptive text). Also remove unused Imports
(conflicted, DT, htmlwidgets, readr, writexl) and Suggests (data.table,
docopt, dtplyr, nipals, readxl, prora) identified during dependency cleanup.
