[Docs] order: update the description of the pathGroupsExcludedImportTypes option

[liby]

Motivation: #2156

#1665 I read this issue and knowing why we had this PR, but I think they use pathGroupsExcludedImportTypes in the wrong way. If we need to let pathGroup works, sometimes we have to add pathGroupsExcludedImportTypes as [].

@Mairu @Akiq2016 @yola-0316 PTAL.
