ANTLR grammar fails to parse tabular subquery on the right of in #194

The KQL docs mention that this is a valid expression:

StormEvents 
| where State in (
    StormEvents
    | summarize count() by State
    | top 5 by count_
    ) 
| count

The KQL ANTLR grammar in the repo fails to parse it:

line 5:4 mismatched input '|' expecting {')', ','}
line 7:4 mismatched input ')' expecting {<EOF>, ';'}

This seems to be due to this line in Kql.g4:

listEqualityExpression:
    Left=relationalExpression OperatorToken=(IN | NOT_IN | IN_CI | NOT_IN_CI | HAS_ANY | HAS_ALL) '(' Expressions+=invocationExpression (',' Expressions+=invocationExpression)* ')';

which may need to be replaced with something like this (extra pipeExpression):

listEqualityExpression:
      Left=relationalExpression OperatorToken=(IN | NOT_IN | IN_CI | NOT_IN_CI | HAS_ANY | HAS_ALL) '(' Subquery=pipeExpression ')'
    | Left=relationalExpression OperatorToken=(IN | NOT_IN | IN_CI | NOT_IN_CI | HAS_ANY | HAS_ALL) '(' Expressions+=invocationExpression (',' Expressions+=invocationExpression)* ')'
    ;

Full repro:

• Install Java 11: https://learn.microsoft.com/en-us/java/openjdk/download
• Install Python 3.14 https://www.python.org/downloads/
• Run pip install antlr4-python3-runtime==4.13.2
• Download https://repo1.maven.org/maven2/org/antlr/antlr4/4.13.2/antlr4-4.13.2-complete.jar
• Run java -jar antlr4-4.13.2-complete.jar -Dlanguage=Python3 -visitor -o out Kql.g4
• Use the Python KQL parser:

  from antlr4 import InputStream, CommonTokenStream
  from KqlLexer import KqlLexer
  from KqlParser import KqlParser
  
  def parse(query: str):
      parser = KqlParser(CommonTokenStream(KqlLexer(InputStream(query))))
      tree = parser.top()
      print(tree.toStringTree(recog=parser))
  
  parse('''
  StormEvents 
  | where State in (
      StormEvents
      | summarize count() by State
      | top 5 by count_
      ) 
  | count
  ''')
