Separate out test case generation from deployment

Rather than looping over branches (in included template from pages), generate the test cases here, provide these as an artifact and deploy in a separate job. This avoids the regeneration of pages that have not changed. Remove the menu generation tools as these are now stored on the pages branch and accessed as an archive.

We need to use the local artifacts from the existing pipeline as these aren't accessible via curl until the whole pipeline has completed.

Whilst we are here, utilise an environment variable for the release to make it easier to migrate this between releases.
