Add jazzy

[christophfroehlich]

let sphinx-multiversion create a page for Jazzy Jalisco, pointing to all rolling/master subrepos. fyi: There is already one at https://docs.ros.org/

@saikishor there is no hurry for merging it, but there won't be any changes necessary unless we branch the subrepos for jazzy

Ofcourse, I agree. If that's the case, we can then merge it.

Let's wait until Jazzy is included in index.ros.org and docs.ros.org/api

The changes seem correct to me though I haven't fully understood the multiversion build, yet.

The core setting is the smv_branch_whitelist: Every branch matching this regex will be built as a version during multiversion build. The other stuff is only for auto-replacement of macros in the docs, as well as checkout the correct branches of the subrepos.

After merging this, I'll rename the default branch of this repo from master to rolling (similar to https://github.com/ros2/ros2_documentation) to make sphinx-multiversion write "Rolling" instead of "Master"

Edit: This will not break old links, I copied the "master" html folder so that one will at least reach something useful.
