mujoco_wasm example not working with latest emscripten version (3.1.61)

[danieldugas]

When using the latest emscripten version (3.1.61), the README instructions

mkdir build
cd build
emcmake cmake ..
make

leads to a build that doesn't run the simple example scene, giving the following error instead:

Uncaught 5582208

Fix: Using emscripten version 3.1.37 solved this issue, installed according to https://emscripten.org/docs/getting_started/downloads.html
