Now using proprietary styles for the user guide - not shared with docs. We are able to better isolate and fix issues with the user guide header without having to touch antora.
This provides a secondary tailwind config that does not do a reset and only includes styles compiled from header and footer templates.
Run `yarn builddocs` to generate the stylesheet for docs
* Removed postcss and postcss-cli because it’s not needed in latest versions of Tailwind cli.
* Now using tailwind cli for dev and build
* Added cssnano. For now I’m not seeing much if any reduction in size but as it grows we might.
