fix(DB\Texts): Goblin pit crew's gossip probability (#9905)

* fix(DB): Goblin pit crew's gossip probability

- Since these guys have 5 possible gossip options, setting this to 25
  each option will equal to 100 percentage.
- There are plenty more gossips like this one only have % of 1 to show
  that need to me manually fixed since we don't know how many npc_text
  they may have. A query to count the text_x_x and update the according
  % should be good to go, however this way is safer.
