tests: Add unit tests for zowex package and SSH VSCE integration

[traeok]

Proposed changes

Implements a comprehensive set of unit tests across the zowex-for-zowe-explorer package to validate SSH API behaviors and integration with Zowe Explorer.

Also fixes an issue with the SshUssApi.updateAttributes function where the success flag was never updated to true, as it was default-initialized to false and only later assigned with &&=.

Release Notes

Milestone: 3.6.0

Changelog (for bug fix): Fixed an issue with the updateAttributes function in the SshUssApi class that caused the API's success property to always return false.

(No changelog for tests)
