Fix references to XR_ENV_BLEND_MODE_ALPHA_BLEND in openxr_passthrough.rst

Browse Source 
The code example at the end of the openXR passthrough tutorial refers to the `XR_ENV_BLEND_MODE_ALPHA_BLEND`  constant. That constant, however, is not accessible in the scope. Instead, it is a member of the `xr_interface` object.

We need to check if ``XR_ENV_BLEND_MODE_ALPHA_BLEND`` is present in this list.
If so we can tell OpenXR to expect an image that can be alpha blended with a background.
To do this, we simply call ``set_environment_blend_mode(XR_ENV_BLEND_MODE_ALPHA_BLEND)``.
To do this, we simply call ``set_environment_blend_mode(xr_interface.XR_ENV_BLEND_MODE_ALPHA_BLEND)``.
We must also set ``transparent_bg`` to true to ensure we submit the right image.
