Updates the determineNodeVersions script to test against all supported versions.
This uses the Node release schedule json

Uses the exact node version specified by lts/* or by NODE_VERSION_OVERRIDE. Uses semver majors for the rest.

Allows you to skip versions by setting NODE_DISABLE_VERSIONS in an org or repo. Example:

Examples
