Update Emsdk atleast to 3.1.56 - fixes SSL errors

[AuderixDev]

What would you like to be added

An update of the Emsdk would be really nice.
Lately they fixed an SSL Error: emscripten-core/emsdk#1357
They now prefer curl over urllib : emscripten-core/emsdk#1355

Why is this needed

The old version causes an SSL Error (on Windows-Docker, while building the WASM)

For which platform

WebAssembly

Anything else we need to know?

No response

Thanks for the report. This is going to be a tricky issue. We cannot reliable upgrade to a later version of emscripten without incurring possible binary breaking changes to generated webassembly binaries, and it needs to be aligned with all the other libraries that have been built around the current version (skiasharp is a good example).
