ScriptDom parser for Sql Server 2022 fails to parse LAG/LEAD with IGNORE NULLS clause

• DacFx Version: 161.6374.0 (Nuget)
• .NET 7
• Windows 11

Steps to Reproduce:

After https://github.com/microsoft/DacFx/issues/133, the parser can parse IGNORE|RESPECT NULLS for FIRST_VALUE/LAST_VALUE but it still doesn’t parse for LAG/LEAD

using Microsoft.SqlServer.TransactSql.ScriptDom;

var parser = new TSql160Parser(true); //sql server 2022 parser
IList<ParseError> errors;

parser.ParseExpression(new StringReader("FIRST_VALUE(col) IGNORE NULLS OVER()"), out errors);
parser.ParseExpression(new StringReader("LAST_VALUE(col) IGNORE NULLS OVER()"), out errors);
//no parsing errors

parser.ParseExpression(new StringReader("LAG(col) IGNORE NULLS OVER()"), out errors);
parser.ParseExpression(new StringReader("LEAD(col) IGNORE NULLS OVER()"), out errors);
//parsing error! "Incorrect syntax near IGNORE." This should parse succesfully

Console.ReadLine();

(p.s.: Please open source the ScriptDom lib. It is full of bugs).
