Update project.url in pom files for documentation migration project

Changes the document.url field in each submodules' pom.xml to point to instead of https://wiki.jenkins-ci.org/display/JENKINS/Blue+Ocean+Plugin. This is the same URL as put into the aggregator by @MarkEWaite in PR2040.

@kshultzCB For something like this, where your PR requires another PR (the file https://github.com/jenkinsci/blueocean-plugin/blob/master/blueocean/doc/BlueOcean.adoc doesn't exist currently), you can start your PR using the other PR as the base, and then add commits on top of it and submit a PR that has the original commit in addition to your commits.

I'm a little surprised this was merged. Blue Ocean is composed of multiple plugins. I assumed in #2040 (comment) that each plugin would have its own adoc page which described the role of that specific plugin within the system that is "Blue Ocean".

Is this a temporary state where those documentation URLs for the component plugins will eventually be replaced by separate adoc pages or is this intended to be the final state?

I realize that it is much more work to provide an adoc description for each of the plugins that are released from this repository, but I thought that would be better for the user than having all the Blue Ocean plugin docs say the same thing.

As far I can see the current change is doing the same as today (i.e same page for all modules/plugins) so at this stage it's at least better :) as this is now a page we can update.
Sure that would be better let's see if we can find some people to contribute this documentation.

Thanks for the clarification @olamy ! I had mistakenly assumed that there were already wiki pages for each of the blue ocean plugins.
