Adds hydroponics shrubs, allowing botanists to grow hedges. (#55496)

Replaces one of the rainbow seeds in the exotic seeds crate with a pack of shrub seeds.
Adds a new, growable seed species for shrubs. Shrubs, when planted (similar to kudzu!) plants a solid, weak barrier in hedges.
These hedges block vision, unless trimmed. Thankfully, we already have a hedge trimming skillchip, so using a sharp implement on the hedge will make it non-opaque.
