replace hexwall code introduction

[avallecam]

In #104 we introduced the hexwall as figure, but we intended to do it as in the main website in https://epiverse-trace.github.io/

if we want this to react as in the main website, this code needs to inherit the CSS from epiverse website to the epiverse copy of {varnish} to reuse that CSS

library(tidyverse)

# turn on if maintainers manage to
# adapt css from main page to varnish
pkg_list <- c("readepi","cleanepi","linelist","epiparameter","episoap")

# from https://github.com/epiverse-trace/epiverse-trace.github.io/blob/main/index.qmd

pkg_path <- "https://raw.githubusercontent.com/epiverse-trace/epiverse-trace.github.io/main/_data/epiverse_pkgs.csv"
hexwall_path<- "https://raw.githubusercontent.com/epiverse-trace/epiverse-trace.github.io/main/_templates/hexwall_element.Rmd"
