CodeQL action have warning

Node.js 16 actions are deprecated. Please update the following actions to use Node.js 20: actions/checkout@v2, github/codeql-action/init@v1, github/codeql-action/autobuild@v1, github/codeql-action/analyze@v1. For more information see: https://github.blog/changelog/2023-09-22-github-actions-transitioning-from-node-16-to-node-20/.

Currently the project uses node version 14. We have to update node to version 20, test all works fine, fix a potential problems and update engines in packages.json. Also, let's mention dev requirements in the docs, we should add info about node version, docker and another tools that are required to make build

Is there a way to benchmark performance currently? It might be interesting to see speed changes after upgrading to node 20.

I think we currently no have benchmarks. We should update node just because 14 version is deprecated and do not supported anymore. I will try to add more unit tests in future, it will be useful additionally for measure performance between node versions too.

Potentially, we may have a problems with build the code with a new node version

How do you test ./Dockerfile and thirdparty/bergamot/Dockerfile?

We just run a command make buildAll that build all things. If this command fails, then we have broken code
