Fix ADO CI build (#212)

This pull request updates the build step in the Azure DevOps CI pipeline
to ensure the correct build configuration is used during the build
process.

Pipeline configuration improvement:

* The `dotnet build` command in `.azdo/ci.yaml` now explicitly uses the
`$(buildConfiguration)` variable for configuration, ensuring builds are
run with the intended settings.
