Config filename typo: `gx5_25.yml` vs `gx5_15.yml`

[GreatAlexander]

Describe the bug Minor filename typo. Config file should be gx5_15.yml not gx5_25.yml in the gx5_15 folder (ros2 branch). https://github.com/LORD-MicroStrain/microstrain_inertial/blob/ros2/microstrain_inertial_examples/config/gx5_15/gx5_25.yml

To Reproduce Launch the gx5_15 example launch file which points to a non-existent file.

Expected behavior Example launch file works correctly

Environment (please complete the following information):

• OS: Ubuntu 22.04
• Architecture: Docker [ros:humble-ros-base-jammy]
• ROS Version: Humble
• Version: Latest ros2 branch [source]
• Sensor(s): 3DM-GX5-15

Additional context While setting up our own launch repo based on the examples, we noticed this naming inconsistency. Apologies if this is not the right process / we've missed something.
