[CI] Add jazzy 🚀

[christophfroehlich]

• Jazzy jobs + readme
• because all of the repos file are empty, there was no difference between binary and semi-binary. So I deleted also the semi-binary workflow file.

Jobs for jazzy-main are failing, but jazzy-testing works fine already.

Rest looks good to me :)

@saikishor I haven't questioned this, just added jazzy. But you are right, it works without specifying a repos file. And because all of them are empty, there was no difference between binary and semi-binary. So I deleted also the semi-binary workflow file.

Edit: nope, only ICI works without the repos file. I have to change the other imported workflows from ros2_control_ci to work without a given repos file.

Looking good to me. Thanks for the changes :)
