bump node.js to currently supported LTS version

[RGHANILOO]

hello @mluukkai , apologies for the pinng

Issue:
based on a recent discussion on Discord regarding local setup issues, I looked into current environment configuration. It seems the project is still pinned to Node v10.18.1 (via .nvmrc) and is utilising Node 10.x in CI workflows.

Node 10 reached EOL in May 2020 and has not received security patches since April 2021. To improve local stability and ensure the project remains secure, there maybe a need to bump the version to a modern LTS release.

proposed changes:

Update .nvmrc to a supported LTS version (e.g., v20.x or v22.x).

Update CI/CD workflow YAML files to reflect the new version.

Update package.json engines field. (Currently not listed)

Audit and update dependencies that is likely to conflict with the version jump.

likely impact:
Since this is a significant jump, it's expect some breaking changes in dependency tree. initial spike will likely identify which packages require upgrades to remain compatible with a modern Node environment.

I already tried this for Node 14, and it was too hard...
The material is about to migrate to a different platform (part 13 is already migrated), so it is probably not worth going throug the pain of node version bump

oooh that makes sense, it just came up in a conversation and i was poking around to see if i could build locally, when i was prompted to download node 10.x, so decided to dig around a bit more.
thanks for update and response on the issue
