Description
## Issue template
This is a feature request. ROS 2 Rolling and [Jazzy depend on Fast-CDR 2.2.x](https://raw.githubusercontent.com/ros2/ros2/jazzy/ros2.repos). [Version 2.4.3 of Micro-XRCE-DDS-Agent](https://github.com/eProsima/Micro-XRCE-DDS-Agent/tree/v2.4.3) supports this but the GIT_TAG in the SuperBuild.cmake in the `rolling` branch refers to `ros2`
#### Steps to reproduce the issue
- Create a `colcon` workspace to build this repo, and source ROS Rolling before building.
#### Expected behavior
- micro-ROS-Agent will build in a `colcon` workspace that has sourced ROS Rolling.
#### Actual behavior
- micro-ROS-Agent will not build in a `colcon` workspace that has sourced ROS Rolling.
#### Additional information
Looks like this will require code changes as well, as micro-ROS-agent will not build against the updated Fast-CDR version. For example:

Piste de recherche
Commencez par SuperBuild.cmake dans la branche rolling et examinez le GIT_TAG de Micro-XRCE-DDS-Agent. Reproduisez le colcon build après avoir sourcé ROS Rolling, puis examinez graph_typesupport.cpp et les correctifs de la branche référencée prs/pr-rolling-fastcdr-2.2.x. Le travail est terminé lorsque l’agent se compile avec Fast-CDR 2.2.x pour la branche ROS 2 demandée.
