fix code snippet in 'Collection lookups with spans (What's new in .NET libraries for .NET 9)' documentation #8033

	# This GitHub Action workflow is triggered on label changes for pull requests.
	# When a pull request is labeled with "DO NOT MERGE", the workflow fails, thus
	# preventing the pull request from being merged. Otherwise, the workflow will
	# succeed, allowing the pull request to be merged.
