PRoblem with Literal Blocks??

[DynConcepts]

THe following snippet passes external validation/lint.... but fails...

`- task: manognaalla.ppmsigntool-task.PPMSignTool.PPMSignTool@4
displayName: 'Run PPMSignTool on CompressionUtils.dll'
inputs:
FilePath: 'bin$(BuildPlatform)$(BuildConfiguration)\CompressionUtils.dll'
ConfigInput: InlineArg
CompanyName: 'Hexagon, Hexagon PPM'
ProductName: 'HxGN 3D GDS'
LegalCopyRight: |

Arguments: force
SHA256: false

condition: and(succeeded(), eq(variables['BuildConfiguration'], 'Release'))
`

Throws exception when it encounters the "A" in Arguments...

if (isLiteral && indentOfFirstLine > 1 && currentIndent < indentOfFirstLine - 1) { // W9L4 throw new SemanticErrorException(end, cursor.Mark(), "While scanning a literal block scalar, found extra spaces in first line."); }

Thanks for the yaml example, it's much appreciated. I have simplified it down to a very small yaml example that breaks.

using YamlDotNet.Serialization;

var deserializer = new DeserializerBuilder().Build();

var yaml = @"a:
- b: |
    
    
  c: d
";

var a = deserializer.Deserialize<object>(yaml);

another simple example is

// @nuget: YamlDotNet -Version 16.1.2

ToJson("|\n\n  foo\n"); // prints "\nfoo\n"
ToJson("|\n \n  bar\n"); // prints "\nbar\n"

ToJson("|\n  \n  baz\n"); // should print "\nbaz\n"
// but fails While scanning a literal block scalar, found extra spaces in first line.

ToJson("|\n   \n  nope\n");
// fails as expected with While scanning a literal block scalar, found extra spaces in first line.

void ToJson(string s) {
	var deserializer = new YamlDotNet.Serialization.DeserializerBuilder().Build();
	try {
		var json = System.Text.Json.JsonSerializer.Serialize(deserializer.Deserialize<string>(s));
		System.Console.WriteLine(s);
	} catch (System.Exception e) {
		System.Console.WriteLine(e);
	}
}

(formatted so that it can be trivially used in https://dotnetfiddle.net/# )

@EdwardCooke is this considered a bug? Would you accept a PR adding a test and fix for this?
