Fix highlighter consistency

- in some places php would not be highlighted as the `<?php` tag was missing
- in one place there was a duplicate `<?php` tage
- replaced `bash` with `console` for better highlighting
- ensured all console snippets are wrapped within highlighting code
- wrapped ini examples in highlighting code
