Bump version to 3.2-stable \o/

Congratulations to everyone in the Godot community for this awesome new
release, culmination of more than 10 months of development from close to
450 contributors!

Thanks to all involved, whether you contributed code, documentation,
bug reports, translations, community support or donations. You all
played a role in bringing better free and open source game development
tools to the world!

Godot 3.2 includes more than 6000 commits made since the 3.1 release in
March 2019, 3000 Pull Requests have been merged, and over 2000 issues
have been fixed!

This release builds upon the feature set and usability of Godot 3.1,
making it even more stable and powerful, and thus a very mature game
development tool for both 2D and 3D.

Now onwards to the 4.0 with Vulkan and a lot of modernization of the
codebase!

Fixed running the export templates with newer emscripten versions.
