New Underground Biome: Spider Nest

It would be a biome only found in the depths at the level of the deepslate. It would be composed of spider eggs (a little animated) which would be a small source of light to illuminate the atmosphere of the cave (a light similar to the soul torches), and if you break a spider egg without silk touch there is a one in two chance that a spider will appear normal or poisonous. Cobwebs and a new decoration block, the thin cobweb that when walking on it the player does not get stuck in it. connecting to the blocks next to it, changing texture according to the position of the block. Very useful for decoration. And maybe mucus mats. The spider egg can be picked up with a silk touch shovel. Mucus can be picked up with a hoe and I'll let you decide if it requires enchantment for it or not.

The reason for this biome is not only to have an additional biome for the caves & cliffs update but also for the spiders to be a place where they come from and to be their "home".
