intro: include list of packages in classwork

[simonpcouch]

Esp. since the list of packages have now diverged, it might be nice to include the list of packages to install inside of the intro-01 classwork for easy running:

workshops/slides/intro-01-introduction.qmd

Lines 298 to 309 in 8610a04

	#| label: installs
	#| eval: false
	#| echo: true
	# Install the packages for the workshop
	pkgs <-
	c("bonsai", "Cubist", "doParallel", "earth", "embed", "finetune",
	"lightgbm", "lme4", "parallelly", "plumber", "probably",
	"ranger", "rpart", "rpart.plot", "rules", "splines2", "stacks",
	"text2vec", "textrecipes", "tidymodels", "vetiver")
	install.packages(pkgs)

I was about to do this and then thought about how we'll have to make sure the list is correct in then three places. I'm gonna leave this open for the moment to collect more opinions but I can see good arguments for either decision.
