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

* ci: update runners

Signed-off-by: Ramon Roche <mrpollo@gmail.com>

* Add docs/en

* Add docs assets and scripts

* Fix up editlinks to point to PX4 sources

* Download just the translations that are supported

* Add translation sources for zh, uk, ko

* Update latest tranlsation and uorb graphs

* update vitepress to latest
