Switch test expect_snapshot to explicit expect_warning #27

	# Workflow derived from https://github.com/r-lib/actions/tree/v2/examples
	# Need help debugging build failures? Start at https://github.com/r-lib/actions#where-to-find-help
	#
	# NOTE: This workflow is overkill for most R packages and
	# check-standard.yaml is likely a better choice.
	# usethis::use_github_action("check-standard") will install it.
