refactor: update parameter names

[ktro2828]

Description

This pull request refactors the way ONNX model paths and parameter files are handled across multiple project configurations and launch files. The main goal is to standardize variable names and improve clarity by replacing generic path variables with more descriptive ones, and by adding helpful descriptions to launch arguments.

Key changes include:

• Replacing the use of data_path with directory/onnx for specifying ONNX model directories in parameter files.
• Updating launch files to use file/parameter and directory/onnx argument names, along with adding descriptions for better readability and maintainability.
• Ensuring all launch files and parameter files across projects follow this new convention.

The most important changes are:

Standardization of ONNX Model Path Variables:

• All parameter YAML files now use $(var directory/onnx) instead of $(var data_path) to specify the ONNX model location, improving clarity and consistency for model directory references. [1] [2] [3] [4] [5] [6] [7] [8] [9]

Refactoring and Documentation of Launch Arguments:

• Launch files now use file/parameter and directory/onnx as argument names instead of param_path and data_path, and each argument is supplemented with a clear description, making the launch files more user-friendly and self-documenting. [1] [2] [3] [4] [5] [6] [7] [8] [9]

Consistent Parameter Passing in Launch Files:

• All <param from=...> tags in launch files now reference $(var file/parameter) instead of the old variable, ensuring consistency in how parameter files are loaded. [1] [2] [3] [4] [5] [6] [7] [8] [9]

Improved Argument Documentation:

• All launch arguments (such as input/output topics, use_raw, build_only, visualize) now include descriptions, making it easier for users to understand their purpose. [1] [2] [3] [4] [5] [6] [7] [8] [9]

These changes collectively improve maintainability, readability, and usability of the configuration and launch files across all supported projects.
