Subject: [PATCH] Fix -Werror build of rpy_publisher

Passing {} as the default value to declare_parameter<std::vector<std::string>>
triggers "converting to ParameterDescriptor from initializer list would use
explicit constructor" under -Wall -Wextra -Werror, which CI uses. Spell out
the default as std::vector<std::string>{}.
