/**
* Compare SemVer versions.
*
* NOTE: SemVer could have been the perfect library to use here but we can't use it since it's meant for `Node` only
* `compare-versions` works for browser but seems way overkill, especially when the version format is very
* standard, i.e. `x.y.z`, no prerelease, etc.
* As such, we can use the lean comparison algo using `localeCompare` with numeric settings
*
* See https://stackoverflow.com/questions/55466274/simplify-semver-version-compare-logic/55466325#55466325
* See omichelsen/compare-versions#45
