[ISSUE]: Better error handling in Azure

[mc0re]

Prerequisites

• I have written a descriptive issue title
• I have searched issues to ensure it has not already been reported

GitVersion package

AzureDevops task

GitVersion version

6.5.1

Operating system

Windows

What are you seeing?

When there is some error when running GitVersion, the Azure package simply reports:

##[error]GitVersion output is not valid JSON

It'd be better to actually show the error.
This is the actual log.

Running on: 'Azure Pipelines'
Disable Telemetry
Command: git -C D:\a\1\s rev-parse --is-shallow-repository
Command: C:\hostedtoolcache\windows\GitVersion.Tool\6.5.1\dotnet-gitversion.exe --roll-forward Major D:\a\1\s /output json /l console /config D:\a\1\s\ci\GitVersion.yml
##[error]GitVersion output is not valid JSON
dotnet-gitversion Output:
-------------------
undefined
-------------------
undefined

What is expected?

GitVersion actual error.

Steps to Reproduce

Please create a pull-request. If you improve the logic it would be a pleasure for me to approve it.

Hm, I cannot reproduce the error any more, something changed in the system. But as a nice detail, I would change the text on line 70 in runner.ts:

return this.handleOutputError('GitVersion output is not valid JSON, see output details')

to

return this.handleOutputError('GitVersion execution failed, re-run the task with Diagnostic flag on to see the details.')

For I myself didn't realize that there could be more output in the debug mode until I saw it in the code :-)
