• [ ] add the requirements to the section/file associated with message queues in a sdoc file, if no section or file exists, add new section (https://github.com/zephyrproject-rtos/reqmgmt/tree/main/docs/system_requirements) or file (https://github.com/zephyrproject-rtos/reqmgmt/tree/main/docs/software_requirements)
