Prepare for 11.13.0 release

[traversaro]

I tought a release could be useful for downstream package mantainers, especially the ffmpeg 6 and gcc 11 fixes. I tried to prepare the Changelog.md (manually, not sure if there is a smarter way) and the CMake change looking at the past PRs, please correct me if I did something wrong. @scpeters @j-rivero

I added "A contribution from" for people outside former OpenRobotics or usual contributors, but I could have missed something.

Comparison to 11.12.0: gazebo11_11.12.0...traversaro:gazebo:rel1113

There are some instructions here that can help to generate a draft version of the changelog entries for the new release but usually requires some manual effort to clean up and remove invalid entries.

we are planning to merge #3325 today; I'll get back to you with next steps after that

the documentation for the next steps in the release process is in the README for release-tools:

• https://github.com/gazebo-tooling/release-tools#making-releases

this PR has completed step 2 of the following workflow:

• https://gazebosim.org/docs/garden/releases-instructions#for-each-release

If you are interested in learning this process, step 3 is to update the debian metadata in
next is to update the debian metadata in https://github.com/gazebo-release/gazebo11-release

In step 4, there are steps that require additional permissions (upload to s3, start jenkins builds), so I need to ask @azeey and @nuclearsandwich what is our policy for granting those permissions.

Thanks for the details! I was a bit naive and I was not aware of all this steps and required permissions, at this point probably if you like feel free to proceed with the release, then we can sort out this indipendently, without blocking the release.

Sure thing I will take care of this release. We are also working to revamp the release process and will wait to onboard new release engineers after we have reduced the scope of required permissions
