(#1039) Improved flow for cases when chocolatey is not installed

[LeaDevelop]

Description Of Changes

The change has following affects:

• Proper error propagation
• Error messages are captured in logs
• Failed state is correctly reported
• Error handling mechanisms work as expected
• Doesn't break the automation tool's PowerShell session

Motivation and Context

With this correction script will stop and not attempt to install the chocolatey server.
Automated approach will recognize error and for manual options user is able to spot error and logs as PowerShell's window remains open.

Testing

• I have previewed these changes using the Docker Container or another method before submitting this pull request.

Change Types Made

• Minor documentation fix (typos etc.).
• Major documentation change (refactoring, reformatting or adding documentation to existing page).
  • It's a minor script improvement, wasn't sure where to put it so I chose this option
• New documentation page added.
• The change I have made should have a video added, and I have raised an issue for this.
  • Issue #

Change Checklist

• Requires a change to menu structure (top or left-hand side)/
• Menu structure has been updated
