Increase maximum number of sub categories under a category in Forum

[Songoku1691]

Hello Guys:

Currently, you can only create a maximum of 5 sub categories in a category in Forum. This limit resulted to having 2 WG categories (Technical and Non-Technical):

1. https://pioneerapp.xyz/#/forum/category/33
2. https://pioneerapp.xyz/#/forum/category/34

Suggestion: Increase this limit of sub-categories. 5 seems to be small.
