This PR updates multiple documentation files to improve clarity, consistency, and readability in the ROS 2 docs. The changes address several suggestions from Issue #1487 and include:

  • Revised the wording in the rclpy package section to clarify that the use of the rcl API maintains consistency across client libraries.
  • Reorganized the "Using Components" section to list the three common approaches (runtime via generic container, compile-time custom executable, and launch file approach) in a numbered format for better clarity.
  • Updated the default RMW implementation text to clearly indicate that Fast DDS is selected as the default if available, and fallbacks are handled alphabetically.
  • Modified the instructions for creating a new ROS 2 package to reference the common workspace setup (usually ~/ros2_ws/src), aligning with standard naming conventions and avoiding project-specific names.
  • Enhanced the Installation Troubleshooting section by restructuring the multicast configuration details to clearly separate general instructions from platform-specific tips (notably avoiding Linux-specific commands on Windows).
  • Reordered elements on the index page: moved Concepts after Tutorials, and refined the descriptions under "Where to start" and in the "Contributing" bullet section to clarify that both code and non-code contributions are welcome.
  • Clarified wording on workspaces by separating definitions for underlay (core ROS 2) and overlays (subsequent local workspaces).

These enhancements aim to make the documentation more user-friendly and less ambiguous, ensuring essential details are easily understood.

All changes have been applied without introducing new packages or breaking tests.

…nt-Middleware-Vendors.rst, Developing-a-ROS-2-Package.rst, Installation-Troubleshooting.rst, Configuring-ROS2-Environment.rst, index.rst): update documentation for clarity and consistency

Improve clarity in the documentation by rephrasing several sections across various files. Changes include enhancing the description of the ROS 2 workspace concept, refining the explanation of the default RMW implementation, and improving the instructions for creating a ROS 2 package. Additionally, update the installation troubleshooting section to provide clearer guidance on enabling multicast. Overall, these updates enhance the readability and consistency of the ROS 2 documentation.

#. Create a launch file and use ``ros2 launch`` to create a container process with multiple components loaded.
The composition can occur at:

* **Compile time**: Create a `custom executable <https://github.com/ros2/demos/blob/{REPOS_FILE_BRANCH}/composition/src/manual_composition.cpp>`__ containing multiple nodes which are known at compile time. This approach requires that each component has a header file (which is not strictly needed for the other cases).

i do not like breaking the sections like this especially for trouble-shooting. i think it would be more useful to keep the trouble-shooting one by one to put all the information together. if that is recognized to Linux specific trouble-shooting maybe we can add the trouble-shooting for other platforms in here?

Hey, FYI this is one of the first few batches of RepoBird demo runs and so I have no way of automating the process of PR review fixes. The actual github app allows me to run @RepoBirdBot commands to fix any PR issues but you don't have the app installed so webhooks that normally trigger the bot wont work. I'll be figuring out a new way to give some review runs that take into account your review comments and update new pushes to this PR source branch. Will keep you posted.

Add additional entries to .gitignore to ignore common build artifacts
and virtual environments. Improve documentation clarity by adjusting
formatting in several guides for better readability and understanding.

Ok, I was able to create a script that scrapes all PR github comments + review comments + pipeline failure logs. I then summarize them to try to distill the main pain points and pass that as a new prompt for the bot to work on. Hopefully linting checks are passing now and the comments have been addressed. Can always re-trigger a new run now as well if any new review comments come in.
