Terraform-provider-azuredevops: Using outdated Go version 1.12.10 in GitHub Pipeline

[tmeckel]

Why is the GitHub pipeline, used to validate Pull Requests, utilizing an outdated Go version 1.12.10, although the build pipeline at the former repository at Microsoft is using at least Go 1.13.1.

The pipeline is now failing on my PR #18 because I'm using the %w formatting statement to wrap an inner error.
