This commit implements support for the 'or' operator in 'when' clauses
of case statements, matching the official Shopify Liquid specification.
Changes:
- Modified expressions.y grammar to accept 'or' as an alternative
separator to commas in the expr2 rule for when statements
- Regenerated y.go parser from the updated grammar
- Added comprehensive test cases for 'or' operator usage:
* Integer values with 'or' operator
* String values matching Shopify documentation examples
* Multiple 'or' operators (e.g., 1 or 2 or 3)
The implementation now supports both syntaxes as specified in the
Shopify documentation:
- Comma-separated: {% when 1, 2 %}
- OR operator: {% when 1 or 2 %}
- Multiple ORs: {% when 1 or 2 or 3 %}
All existing tests continue to pass, confirming backward compatibility.
