[Rel21] update scripts fails

The new description is too long

Hi, I tried to update release21 mangos database.

For the following scripts, the update fails :
Rel21_2_2_Windrunner_Spire_NPCs.sql
Rel21_2_3_Zaxxis_NPCs.sql
Rel21_2_4_Crust_Busters.sql

The reason for all scripts is the new description is too long.
@cNewDescription is more than 30 characters length
I suggest the following descriptions :
SET @cNewDescription = 'Windrunner Spire NPC fixes';
SET @cNewDescription = 'Zaxxis NPCs aggressive';
SET @cNewDescription = 'Wrong CrustBusters UnitFlags';

ps : 'affected version' should be updated for issue posting
