show we add the full installation script for EpiNow2?

[avallecam]

In the setup we have

tutorials/learners/setup.md

Lines 52 to 62 in 35b34d4

	if(!require("pak")) install.packages("pak")
	new_packages <- c(
	"EpiNow2",
	"epiverse-trace/epiparameter",
	"socialmixr",
	"epiverse-trace/epidemics",
	"tidyverse"
	)
	pak::pak(new_packages)

but in episode, we had as suggestion:

library("devtools")
install_version("EpiNow2", version = "1.4.0", repos = "http://cran.us.r-project.org")

any drawback to using pak just directly?
