Move PX4 Guide source into /docs (#24490) 
* Add vitepress tree

* Update existing workflows so they dont trigger on changes in the docs path

* Add nojekyll, package.json, LICENCE etc

* Add crowdin docs upload/download scripts

* Add docs flaw checker workflows

* Used docs prefix for docs workflows

* Crowdin obvious fixes

* ci: docs move to self hosted runner

runs on a beefy server for faster builds

ARK Pixhawk Autopilot Bus Carrier

:::warning PX4 does not manufacture this (or any) autopilot. Contact the manufacturer for hardware support or compliance issues. :::

The ARK Pixhawk Autopilot Bus (PAB) Carrier is a USA-built flight controller carrier board, based on the Pixhawk Autopilot Bus open source standard.

The PAB form factor enables the ARK PAB Carrier to be used with any PAB-compatible flight controller, such as the ARKV6X.
