Add berry bushes to #farm

## Describe your suggestion
Baritone doesn't farm berry bushes. Please add the bush to the list of farmables, and make sure that Baritone doesn't walk through the bush, and also doesn't left click on the bush. Make sure that it right clicks.

## Settings
None, but https://github.com/cabaletta/baritone/issues/893 should apply to the bush, too

## Context
Kind of obvious...

## Final checklist
- [owo] I have not used any OwO's or UwU's in this issue.

No files, tests, or entry points are named in the issue. Start by locating the farmable-block list and the pathing and interaction handling for berry bushes, then review issue #893 for the related behavior. Done means berry bushes are farmed by right-clicking, are not left-clicked, and are not walked through.
