fix(reaction_analyzer): fix include hierarchy of tf2_eigen

[SakodaShintaro]

Description

When I ran the following commands today, I got a lot of ros-humble-related updates.

sudo apt update
sudo apt -y upgrade

After that, when I built autoware, I started getting the following errors.

In file included from /home/shintarosakoda/autoware/src/universe/autoware.universe/tools/reaction_analyzer/include/reaction_analyzer_node.hpp:19,

Looking at the other files in autoware.universe, it seems that tf2_eigen is usually included in a single hierarchy.

autoware.universe/localization/autoware_landmark_based_localizer/autoware_landmark_manager/src/landmark_manager.cpp

Line 22 in 7011ea1

#include <tf2_eigen/tf2_eigen.hpp>

https://github.com/search?q=repo%3Aautowarefoundation%2Fautoware.universe+%3Ctf2_eigen%2F&type=code

So the same change will be made to reaction_analyzer.

How was this PR tested?

I have confirmed that autoware can be built normally in the environment after the ros-humble update.

Let me merge this PR right now without @brkay54 's review since the build of awf/autoware is failing. Thank you.
