👨‍🌾 There's a problem introduced with this PR. ign-gazebo jobs are failing now because this jobs gets ign-rendering@main, that is ign-rendering7 while ign-gazebo@main seems to be requiring ign-gazebo6.
See ign-gazebo@main/CMakeLists.txt#L138.

Reference failing job: https://build.osrfoundation.org/job/ign_gazebo-pr-win/3404

Should this issue be fixed modifying this job or opening a PR for ign-gazebo? @chapulina @scpeters PTAL

Bumping dependency versions is challenging since it leads to breakage with our current CI setup. Things should be unbroken once gazebosim/gz-sim#1183 is merged. If this is affecting open pull requests, we can revert this for now and merge it closer to when gazebosim/gz-sim#1183 is ready for testing

Yeah sorry I merged this too quickly and forgot that Windows uses it. I think it's ok to be in a broken state on some main branches until gazebo-tooling/release-tools#545 is completed.
