Upgrade MAVLink in dependencies.rosinstall

[evan-palmer]

Issue details

The version of MAVLink targeted in the dependencies.rosinstall file (i.e., release/foxy/mavlink) does not include the latest changes to pymavlink needed to support Python 3.12 (available in this commit from Tridge). These changes are needed to help address #1958.

@vooon is there anything I can do to help with this? I took a look at the mavlink-gpb-release repo, and it looks like the bloom build needs to be manually triggered?

So 2024.6.6 should have it.

NOTE: this is the correct one for ROS2: https://github.com/ros2-gbp/mavlink-gbp-release

Foxy is EOLed, and no release accepted to EOLed distros.

Oh perfect! I hadn't seen that repo. I just did some testing, and things work as expected with Jazzy. Thanks!
