Update maintainers across ROS packages

[yeseorizi]

Summary

• add Woen-Sug Choi (wschoi@kmou.ac.kr) as a maintainer to all 13 ROS packages
• add Ye-Seol Kwon (kys50728@g.kmou.ac.kr) as a maintainer to all 13 ROS packages
• preserve the existing package maintainers and normalize the existing Woen-Sug Choi entries to the institutional address

Validation

• parsed all 13 package.xml files as XML
• confirmed exactly one entry for each newly standardized maintainer in every package
• git diff --check passed

This PR only updates package metadata and does not change runtime behavior.

The GitHub lint failure is unrelated to the package.xml changes: the hosted runner used a stale apt index and received HTTP 404 while installing libxml2-utils. PR #71 refreshes apt indexes before system dependency installation and its lint workflow passes. The package metadata itself also passes pre-commit.ci and all 13 manifests parse successfully as XML.

Manifest and integration validation update

• All 13 package.xml files parse successfully as XML.
• Each manifest contains exactly one institutional entry for Woen-Sug Choi <wschoi@kmou.ac.kr> and one for Ye-Seol Kwon <kys50728@g.kmou.ac.kr>.
• Existing third-party maintainers were preserved.
• This PR was included in a local pre-merge candidate with Fix BlueROV IMU bridge for ArduSub SITL #66–69 and the apt-index fix in Refresh apt indexes before CI and Docker dependency installs #71. The resulting native ARM64 Docker image built successfully, and all 14 executable public Quickstarts passed with graceful shutdown.

The red GitHub lint check on this PR is the stale apt-index 404 already addressed by #71; pre-commit.ci passed and the manifest contents were revalidated locally.
