ci: a couple more labeler rules

[casswedson]

Summary

None

Purpose of change

I saw some places where this can improve, for instance this baby isn't performing super ultra good or whatever in the case of the spawn and items: armor regex rules, the underlying magic is, like always hard to understand but it works casswedson#82

also remove a couple s here and there; be more generic if it's beneficial
(there's only one conducts file soooo)

Describe the solution

add specific regex targeting directories like **/armor/** and **/monstergroups/** along with substrings like **armor** or **monstergroup**

Describe alternatives you've considered

Testing
