docs(sim): add Try PX4 quick-start and pre-built packages reference (#26957)
Adds documentation for the SITL containers and .deb packages introduced in #26495. The containers are now live on Docker Hub: [`px4io/px4-sitl:latest`](https://hub.docker.com/r/px4io/px4-sitl) and [`px4io/px4-sitl-gazebo:latest`](https://hub.docker.com/r/px4io/px4-sitl-gazebo).

The main addition is a [Try PX4 Simulation](https://docs.px4.io/main/en/dev_setup/try_px4) page that leads with a single `docker run` command and gets someone flying in under a minute. It lives in Getting Started, right after Recommended Hardware/Setup, so it's one of the first things new users see.

The existing `.deb` package reference has been moved from `packaging/px4_sitl_deb.md` to `simulation/px4_sitl.md` and expanded to cover both containers and `.deb` packages on one page. Sections are ordered by how people use them: what's available, install, configure, connect QGC/MAVSDK, connect ROS 2.

Other changes:
- README now has a "Try PX4" section with the docker one-liner above "Build from Source"
- Landing page (`index.md`) reworked to lead with "Try PX4" before "For Developers"
- Toolchain page (`dev_env.md`) gets a tip redirecting simulation-only users to pre-built packages
- `getting_started.md` and `SUMMARY.md` updated with links to the new pages
- Simulation index tip updated to mention containers alongside `.deb` packages

The SIH container image is published as `px4io/px4-sitl` (renamed from `px4io/px4-sitl-sih`) so the default lightweight option carries the simplest name. The Gazebo image remains `px4io/px4-sitl-gazebo`.

Also upgrades all GitHub Actions in the SITL workflow to Node.js 24 compatible versions (`actions/checkout@v6`, `actions/cache@v5`, `actions/upload-artifact@v7`, `actions/download-artifact@v8`, `docker/setup-buildx-action@v4`, `docker/build-push-action@v7`) to fix the Node.js 20 deprecation warning ahead of the June 2026 deadline.

# Setting up a Developer Environment (Toolchain)
::: tip
You only need a toolchain if you want to **modify and build** PX4 from source.
If you just want to run PX4 simulation without changing the code, use a pre-built [Docker container or .deb package](../simulation/px4_sitl_prebuilt_packages.md) instead.
:::
The _supported platforms_ for PX4 development are:
- [Ubuntu Linux (24.04/22.04)](../dev_setup/dev_env_linux_ubuntu.md)
- [Windows (10/11)](../dev_setup/dev_env_windows_wsl.md) — via WSL2
- [macOS](../dev_setup/dev_env_mac.md)
## Supported Targets
The table below shows what PX4 targets you can build on each OS.
| Target | Linux (Ubuntu) | macOS | Windows |
| -------------------------------------------------------------------------------------------------------------------------------------- | :------------: | :---: | :-----: |
| **NuttX based hardware:** [Pixhawk Series](../flight_controller/pixhawk_series.md), [Crazyflie](../complete_vehicles_mc/crazyflie2.md) | ✓ | ✓ | ✓ |
| **Linux-based hardware:** [Raspberry Pi 2/3](../flight_controller/raspberry_pi_navio2.md) | ✓ | | |
| **Simulation:** [Gazebo SITL](../sim_gazebo_gz/index.md) | ✓ | ✓ | ✓ |
| **Simulation:** ROS 2 with Gazebo | ✓ | | ✓ |
| **Simulation:** [Gazebo Classic SITL](../sim_gazebo_classic/index.md) | | ✓ | ✓ |
| **Simulation:** [ROS with Gazebo Classic](../simulation/ros_interface.md) | | | ✓ |
Experienced Docker users can also build with the containers used by our continuous integration system: [Docker Containers](../test_and_ci/docker.md)
## Next Steps
Once you have finished setting up one of the command-line toolchains above:
- Install [VSCode](../dev_setup/vscode.md) (if you prefer using an IDE to the command line).
- Install the [QGroundControl Daily Build](../dev_setup/qgc_daily_build.md)
- Continue to [Building PX4 Software](../dev_setup/building_px4.md).
