Documentation doesnt seem to be updated to the latest version

Im not sure whats happened, but

* https://views.grails.org/latest is stuck at 2.0.4
* https://views.grails.org/2.1.x works
* https://views.grails.org/2.2.x doesnt resolve
* https://views.grails.org/2.1.0 doesnt resolve
* https://views.grails.org/2.1.1 doesnt resolve
* https://views.grails.org/2.1.2 doesnt resolve
* https://views.grails.org/2.2.0 doesnt resolve

this is especially annoying when trying to work out what changes have been made, if any, when updating from previous versions

Start by checking the listed views.grails.org URLs and how the latest and versioned views are published. Done means the latest documentation is current and the reported 2.1.x and 2.2.x version URLs resolve so changes between versions can be reviewed.
