Add job name to .github/workflows/ci-build.yml

[kaklakariada]

github-keeper can only update the branch protection in this repo if a job name is defined in .github/workflows/ci-build.yml:

Validation Error for .github/workflows/ci-build.yml: matrix github-action jobs with object parameters and no job name are not supported. Please add a name field to the job that combines the matrix parameters into a more readable name. For example "Build with Go ${{matrix.go}} and Exasol ${{ matrix.db }}"
