[CALCITE-4390] Fix SqlMatchRecognize operand list

[dawidwys]

The PR fixes the list of returned operands in SqlMatchRecognize. Without the change e.g. SqlShuttle cannot be used with MATCH_RECOGNIZE clause.

LGTM

Thanks for the PR @dawidwys . Some minor details to correct the commit message (as per https://calcite.apache.org/develop/#contributing):

• The commit message should describe the issue, and should not begin with "Fix ...". IMHO the Jira title ("SqlMatchRecognize returns wrong operand list") would be a more adequate commit message.
• The commit message should end with your name & last name in parentheses.

Sorry for not abiding by the guide. I updated the commit message according to your suggestion.
