Fixed directory name case inconsistencies

[atty303]

Description of the problem being solved:

Unable to read StatDescription on case-sensitive systems such as Linux. My case was an error when I tried to add Skill in pob-web.

The directory is capitalized as src/Data/StatDescriptions/Specific_Skill_Stat_Descriptions, but the directory name in the skill data parent is lower-cased.

PathOfBuilding-PoE2/src/Data/StatDescriptions/Specific_Skill_Stat_Descriptions/herald_of_thunder_statset_1.lua

Line 89 in 7cfb8bd

parent="specific_skill_stat_descriptions/herald_of_thunder_statset_0"

I would like to unify this with lower case or capital case.

• To unify to a capital case:
  • You need to patch the parent of the skill data in Export
• To unify to a lower case (this PR):
  • Consistency with other directories is a concern.

Which would you prefer?

Steps taken to verify a working solution:

• This PR will allow you to add your skills in pob-web.
• Windows build still works.
