Subject: [PATCH] Make GenericDialect support trailing commas in projections

Similar to https://github.com/apache/datafusion-sqlparser-rs/pull/1911.

The docs for GenericDialect says that is can be permissive, so I thought
it could support trailing commas in projections.

This would help a bit on the "friendly sql" issue
