fix: validate path for getHomeDirectory

[ivikash]

Problem

• Users with misconfigured env variables -HOME or USERPROFILE or HOMEPATH AWS_SHARED_CREDENTIALS_FILE or AWS_CONFIG_FILE are unable to login into Amazon Q and AWS Toolkits extensions.

Solution

• Added a isValidPath function to ensure a valid path is used for authentication

TODO

• [x] Update fs to fsCommon because the web tests are failing. This entails updating all functions to use Promises
• [x] Updating createVueEntries function to allow developers to build on *NIX and Windows.
• [x] Add Logging

Users on windows are unable to login to AWS Toolkits and Amazon Q extension on Windows because env variable: HOME is set incorrectly

It's not really a Windows specific issue. Any system with a misconfigured $HOME env var could have this issue.
