semver for jsdom in peerDependencies

[alumni]

Currently any jsdom version is accepted because the semver contains the "or" operator (>=10.0.0 || <20 matches everything including 9, 20, 21). To achieve the same result, * could be used instead.

If you want to match everything between 10 and 20 (open interval), the semver should be: >=10 <=20.
