Mineshaft-Like Features Generate More in Straight Spaghetti Caves in 1.18

With the addition of straighter 'spaghetti' caves in 1.18, there will be areas where caves look almost man-mined. So maybe mineshafts, or even simple support beams and the occasional minecart, should be more common in spaghetti caves. This would make an interesting feature and give more reason to explore the otherwise duller straight spaghetti caves.
