Add support for Iron

[hoffmann-stefan]

Adds support for Iron.

This is the equivalent of those two PRs for Humble:

• https://github.com/ros-tooling/setup-ros/pull/484
• https://github.com/ros-tooling/setup-ros/pull/490

Came across this while doing the PR to add Iron CI to ros2_dotnet:

• https://github.com/ros2-dotnet/ros2_dotnet/pull/110

Thank you very much for doing this! I was going to do it eventually, but I'm a bit busy these days.

What version of Node are you using? This failure seems to indicate that there is a mismatch between the version you used to update the index.js file and the expected version: https://github.com/ros-tooling/setup-ros/actions/runs/5072876818/jobs/9111165183?pr=568

Using the following node version on ubuntu 20.04:

$ node --version
v16.20.0

did an npm install (was mising this initialy), npm run fixup and npm run build. Force pushed the amended commit, but didn't change anything...

Thanks for checking. I'll see if I can give it a shot on my end.

This job failure doesn't necessarily mean that something is wrong, but I'll double check.

Done! Released as 0.6.2/v0.6.
