Mark version 1.25 as released today

Blender 3.1 will be shipped with Python 3.10, which made some backward-
incompatible changes in its asyncio module (the removal of the `loop`
parameter from various functions).

Depending on which Python version is used in Blender, the add-on now
passes (or not) the `loop` parameter, retaining backward compatibility.
