Allow Tab Completion in Install Root Prompt

[Trenly]

Description of the new feature / enhancement

When InstallLocationRequired is set to true and the user does not have a default install root set, the user is prompted for an install location. However, this field does not support tab completion of the file path, forcing users to type out the entire path manually. For long paths this can be painstakingly tedious. It would be beneficial to allow paths to be tab completed in the prompt by default.

This behavior is also unaffected by the complete command used with the normal tab completion, so even if the user has tab completion for winget commands enabled, this prompt still must be entered manually
