Tidy up template - move Pages to 'build' section, re-order variants, remove redundant when:never
The pages job is placed in the 'validate' section in main.yml, but the job stage is 'build'. It would be clearer to read if we moved it into the 'build' section in the file.
There are also now several rules and job variants that have next/previous and minor/major but they are not all in the same order. This adds a (small) cognitaive overhead in checking one set against the other. It would ease things if we have all the variants appearing in the same order whenever they are used.
