NTRs & edits required for brush (tuft) cell and subclasses

[Caroline-99]

Edits

• Revise textual and logical defs - brush cell  #2896
• Intestinal tuft cell - improve definition and include the specific marker DCKL1(PMID: 28684459) and its role in chemosnstation in intestine + source of cytokine IL-25 + shown to be specific to mediating type 2 immunity against parasites (https://doi.org/10.1016/j.imlet.2019.02.003).
