fix(list): Do not fetch directory URIs in stat

[traeok]

Proposed changes

There was an oversight when implementing the remote lookup functionality for Data Sets and USS. The stat implementations should never make an API call unless we are explicitly fetching the URI with the fetch query, or if the entry is a file (stat is called for files open in the editor).

Considering this causes a balloon in API calls when listing data sets and USS folders, it would be best to get this fix into the upcoming pre-release, or at the very least get the fix merged before v3 GA so that our users don't encounter this problem 😅

How to test:
NOTE: Please test on a dev LPAR as this may spam the mainframe with API calls
List a large data set in Zowe Explorer. In this PR it will load very quickly - in the last pre-release it will take quite some time to complete (or it won't finish loading at all)

This works great and solves the hang mentioned on call last week retrieving data set members. Thanks @traeok for the fix!
