Cave vines can generate without tip because prioritize_tip option is negated

The Bug:

Cave vines generate without tip if they are generating too long to fit into the cave.

How to reproduce:

Seed: -729051142556713127
Coordinates: /execute in minecraft:overworld run tp @s 737.83 -24.50 -988.88 -127.65 35.25

Travel around that lush cave there and it should happen regularly. Due to MC-219200 it might be in a different place each time

Cause:

The "prioritize_tip" setting of the "minecraft:block_column" feature is behaving the other way around than expected: setting it to false would instead prioritize the generation of the tip.

Expected Result:
The Cave vines would have a tip and wouldn't generate without one
