improvements to slides for 2024 course #3

	name: Render presentation and publish to GitHub Pages

	# Render presentation with Quarto on all merges to main, all pull requests,
	# or by manual workflow dispatch. The build job can be used as a CI check
	# that the presentation still renders successfully.
	# The deploy step only runs when a release tag is pushed to the main branch
	# and actually pushes the generated html to the gh-pages branch
	# (which triggers a GitHub pages deployment).
