Add OS maintenance strategy to documentation #2397
Description
Suggestion
Extend the CONTRIBUTING document to describe the strategy for including and adding new images, either by adding text or referring to a separate new document.
This should reference:
- which operating systems are included (currently Alpine and Debian)
- how / when new operating system versions are added
- how / when operating system versions are removed
- how the default operating system version is set and maintained for a given Node.js release line
