Rename custom_params to custom_keys

[Minipada]

This task consists in renaming:

1. custom_str_param_list to custom_key_str_list node paramter
2. custom_str_params to custom_keys_str node paramter
3. All variables with custom_params to custom_key

The documentation of the parameters are located here https://minipada.github.io/ros2_data_collection/dc/measurements.html#node-parameters

The reason to do so is that we are not adding custom parameters but custom keys to the JSON.

To do it, I would suggest to do a Ctrl-F an do search and replace.

They are located in:
https://github.com/Minipada/ros2_data_collection/blob/humble/dc_core/include/dc_core/measurement.hpp
https://github.com/Minipada/ros2_data_collection/blob/humble/dc_measurements/include/dc_measurements/measurement.hpp
https://github.com/Minipada/ros2_data_collection/blob/humble/dc_measurements/include/dc_measurements/measurement_server.hpp
https://github.com/Minipada/ros2_data_collection/blob/humble/dc_measurements/src/measurement_server.cpp

Then we should also rename them in the documentation. To run the documentation locally and see your changes, check the FAQ https://minipada.github.io/ros2_data_collection/dc/contributing.html#docs
