Fix pre-release and build workflows

Added fix to workflows.
* Added a defaults section to the GitHub Actions workflows (build.yml and pre-release.yml) to set the working-directory to inventory-manager.
## WHY It Matters
- This change standardizes the working directory for the build and pre-release jobs, ensuring that all commands run in the correct context, which can help prevent errors related to file paths.
