Update bbq test data to better distinguish docs (#125705)

Adjust the test data. I verified that the scores are now more
distinguishable when:

 - each doc has its own segment
 - when 1 & 2 are in the same segment but 3 is alone
 - 2 & 3 in the same segment but 1 alone
 - 1 & 3 in the same segment but 2 alone
 - all three in the same segment
