Description

Fixes the Github CI action to build all packages. The previous version only built the Bosun binary, but that doesn't include all packages in this repository. To see that this project builds correctly, we need to build all packages explicitly.
Installs all dependencies (most notably, Typescript) required by the SonarCloud step.
Specifies the path to the report files explicitly so that SonarCloud can use them.
