Feature request

Feature description

discussion https://github.com/ros2/rcl/pull/999#issuecomment-1370387037, it would be better to support yaml tag full support, not only with !!str.

Implementation considerations

Reference implementation can be https://github.com/ros2/rcl/pull/999 which added !!str tag.

yaml tag timestamp, need a regex check, which need compiling in a regex related library, and ros2 parameter type does not support timestamp, do we really need it?
