Simplify web setup related to libolm

[zatteo]

During a setup of Twake Chat for web, I ran into the section about libolm.

It seems to be working when downloading olm.js and olm.wasm from here https://gitlab.matrix.org/matrix-org/olm/-/packages/2190 instead of building it with Docker.

Why do you think ? It seems a lot simpler for me to setup, but I lack the necessary background and maybe it will not work everywhere/everytime ?

IMO, we should keep both guideline for user.

I can add it so we have both. But is there any good reason to the Docker way? Even if I have no background to this library, I do not see the purpose of building it locally if its a web library?

Why close @hoangdat ? Keeping both can be a safe solution, but it was easier and it worked on my local setup by just downloading it from the link. I can create a new PR with both solution.

I tried to follow the Readme but I didn't manage to get the docker running.

I run docker run -v ./assets/js/package:/package nixos/nix:2.22.1 and it's ok, but then the readme say:

# within the docker
...

But I can't go within the docker. Whenever I try to launch the docker, it exited in 2 secondes, without any notice.

This closed PR saves my life.

I also have to:

# change flutter version because the one described in the readme is not the same used in gh actions

# install rustup 
curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh

# add to my path
echo 'export PATH="$HOME/.cargo/bin:$PATH"' >> ~/.zshrc
source ~/.zshrc

# install yq 
brew install yq

And then I had to run :

./scripts/prepare-web.sh

And then, I was able to run the web app.

okie, will look on it next week, because we did not use libolm anymore

Yeah I think it's safe to remove this part about lobolm but we absolutely need to add the step to install rust toolchain
