match processor should handler values other than string properly (#47419) 

Currently if the document being ingested contains another field value
than a string then the processor fails with an error.

This commit changes the match processor to handle number values
and array values correctly.

If a json array is detected then the `terms` query is used instead
of the `term` query.
