Python 3.10.2 installed via Homebrew and this fixed mine:
Environment.SetEnvironmentVariable("EMSDK_PYTHON", "/usr/local/Cellar/python@3.10/3.10.2/Frameworks/Python.framework/Versions/3.10/bin/python3.10");

Thanks for the hint Dmitrov.
So the issue is macOS 12.3 dropped the /usr/bin/python executable.
The version of emscripten in 2020.3 is pretty old but does support python2 or python3.
So the fix for me was to open /Applications/Unity/Hub/Editor/2020.3.31f1/PlaybackEngines/WebGLSupport/BuildTools/Emscripten/emcc in a text editor, and change the first line to: #!/usr/bin/env python3

For a temporary fix, install python 2.7 and then make a pre-build editor script to set the EMSDK_PYTHON env variable.
In my case it looks like this:
public class PreBuildProcessing : IPreprocessBuildWithReport
{
public int callbackOrder => 1;
public void OnPreprocessBuild(BuildReport report)
{
System.Environment.SetEnvironmentVariable("EMSDK_PYTHON", "/Library/Frameworks/Python.framework/Versions/2.7/bin/python");
}
}
