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 Signed-off-by: Ramon Roche <mrpollo@gmail.com> * ci: don't run build action for docs or ci changes Signed-off-by: Ramon Roche <mrpollo@gmail.com> * 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 --------- Signed-off-by: Ramon Roche <mrpollo@gmail.com> Co-authored-by: Ramon Roche <mrpollo@gmail.com>

+# Airspeed Calibration
+
+:::info
+[Airspeed sensors](../sensor/airspeed.md) are highly recommended for Fixed-wing and VTOL vehicles.
+:::
+
+:::warning
+Unlike most other sensor drivers, the airspeed sensor drivers are not automatically started.
+Before calibration they must be [enabled via the corresponding parameter](../advanced_config/parameters.md):
+

+- TE MS4525 ([SENS_EN_MS4525DO](../advanced_config/parameter_reference.md#SENS_EN_MS4525DO))
+- TE MS5525 ([SENS_EN_MS5525DS](../advanced_config/parameter_reference.md#SENS_EN_MS5525DS))
+- Eagle Tree airspeed sensor ([SENS_EN_ETSASPD](../advanced_config/parameter_reference.md#SENS_EN_ETSASPD))

+
+## 执行校准
+
+To calibrate the airspeed sensor:
+
+1. Start _QGroundControl_ and connect the vehicle.
+
+2. Enable the airspeed sensors if not already done (as in _warning_ above).
+
+3. Select **"Q" icon > Vehicle Setup > Sensors** (sidebar) to open _Sensor Setup_.
+
+4. Click the **Airspeed** sensor button.
+
+   ![Airspeed calibration](../../assets/qgc/setup/sensor/sensor_airspeed.jpg)
+
+5. Shield the sensor from the wind (i.e. cup it with your hand).
+   Take care not to block any of its holes.
+
+6. Click **OK** to start the calibration.
+
+7. Once asked for, blow into the tip of the pitot tube to signal the end of calibration.
+
+   :::tip
+   Blowing into the tube is also a basic check that the dynamic and static ports are installed correctly.
+   If they are swapped then the sensor will read a large negative differential pressure when you blow into the tube, and the calibration will abort with an error.
+
+:::
+
+8. _QGroundControl_ then tells you if the calibration was successful or not.
