raidboss: fix p10s jade passage wrong output

[lsl1225]

Just played p10s in games, and it seems the result is opposite, still need someone to take further testing.

Looking back at the original PR (#5574 ) that added this trigger, I think the assumption was that the largest potential y-value for the combatants (114) was lines, but it isn't.

The bits don't align perfectly with boxes or lines - there some vertical drift from north to south. Here's a screenshot showing the bits at [88, 92, 96, 100, 104, 108, 112], and you can see the drift:

Assuming the positioning of the bits in this screenshot is best described as being on 'lines' (which, I guess, is probably as good as we can get) -- then the trigger should return output.boxes!() to tell users to stand inside the boxes. Right now, it returns output.lines!(), so I think this PR is a good fix.

As wexxlee mentioned, it's an approximation. I realize in game if you are at the south end, (last row), it ends up being off whether or not it is lines/boxes, so unless you are middle of the arena, it's iffy how much the change is worth (from the previous PR towards just having said avoid lasers). Unsure if there is anything better it could say.
