Allow customisation of sdist and wheel name patterns for twine

Right now the component:publish twine job just looks for *.tar.* and *.whl, which means that the job will likely fail if there are any other tarballs or wheels in the project directory at runtime, either from the git project itself (unlikely) or brought in from the artifacts of other jobs (more likely).

We should enable customisation of the pattern that is used to discover the files to publish.
