Removing redundant dependencies

If want to update the last version of Font Awesome icons (from 5.15.1 to 6.4.2)

jsdelivr_cdn <- "https://cdn.jsdelivr.net/npm/@fortawesome/"
ft_aws <- paste0(jsdelivr_cdn, "fontawesome-free@5.15.1/")
new_icon_dep <- htmlDependency(
  name = "font-awesome",
  version = "5.15.1",
  src = c(href = ft_aws),
  stylesheet = "css/all.min.css"
)

icon_deps <- list(
  new_icon_dep,
  findDependencies(shiny::icon("th"))[[1]]
)

resolveDependencies(icon_deps)
