[BUG] Add missing level18 in level dropdown #2538

	# We enforce coding standards locally via a pre-commit hook.
	#
	# By using the pre-commit github action, we can re-use all of that logic
	# and have identical checks in Github Actions as we have locally.
	#
	# There is then no need to run e.g. the flake8 linter with a manually
	# created github workflow.
	#
	# Any new linters/autoformatters should be configured in the file
	# .pre-commit-config.json
	#
	# This was rewritten when we introduced the yaml rewriter for the /content/
	# directory.
