Bump version to 3.6-stable \o/

At long last, after 2 years of development, Godot 3.6 is finally out!

Developing it in parallel to the 4.x branch proved to be a challenge,
as eventually I (Rémi) hardly had any time to focus on it.

Thankfully lawnjelly picked up the torch, both on the feature dev side
(most new rendering features are his work) but now also as release
manager for 3.x.

For anyone still using Godot 3.5 for their released or soon-to-be
published titles, upgrading to 3.6 should bring a lot of bug fixes, as
well as a number of useful features and quality of life improvements.
