Description

Three small edits to get the feature/msa

• Fixes XML rendering in README.md
• Removes a TODO for functionality that has not been needed in the ROS 2 port.
• Removes a duplicated header inclusion.

Checklist

• Required by CI: Code is auto formatted using clang-format
• Extend the tutorials / documentation reference
• Document API changes relevant to the user in the MIGRATION.md notes
• Create tests, which fail without this PR reference
• Include a screenshot if changing a GUI
• While waiting for someone to review your request, please help review another open pull request to support the maintainers

Please target the main branch for development, we will backport the changes to feature/msa for you if approved and if they don't break API.

@DLu can you fix the formatting?
