[PSA] Emscripten 6.0.0 released

[Sam Clegg]

Hi all,

We just released emscripten 6.0.0.

Noteworthy changes include enabling dynamic linking by default, and switching Windows entry points from .bat files to .exe files. 

See https://github.com/emscripten-core/emscripten/releases/tag/6.0.0 for all the details.

Note that we are experimenting with using GitHub releases here (previously we were just using git tags).   Is this a good idea?   Feedback welcome!

cheers,
sam
