build.yml

## The workflow will:
##  - create a new version, build the package and run tests
##  - publish a release to npm when you create a new GitHub release.
##  - publish a prerelease to npm from:
##     - main branch
##     - all branches with #deploy_branch in the commit message.
##
## The workflow assumes the following:
##  - package.json has a "version" property
##  - package.json has a "name" with the format "@tfso/<my-package>"
##  - package.json has the following scripts
##    - "build" - build the package into the ./dist folder
##    - "test"
##  - the project is installable with "npm ci"
