Node 10 is the end of life since April 2021. It becomes more and more unsupported by the libraries we use in our different JS project. Until now we had to make a workaround to keep compatibility with node 10.

As for the official EOL of node, we should also drop support for node 10 and stay up-to-date with the libraries that upgraded without node 10 support.

We need to:

• Remove the tests with node.js v10 in the CIs
• Ensure no library has been blocked to avoid losing node 10 compatibility
