Raise the minimum required version of node

[gr2m]

See for reference: semantic-release/semantic-release#2055

• require a minimum node version of the latest LTS, currently 14.17
• ensure engines-strict is enforced in the CI of each project to reduce the cases where incompatible dependencies are installed outside of our supported range (example)
• Make sure to update the docs if we mention a minimal node version anywhere

Bonus:

• Make it a native ES Module, but wait until we decided to go with a native ESM module as part of Raise the minimum required version of node in semantic-release/semantic-release semantic-release#2055
