Package ships no license file and its upstream repository
(https://github.com/tvdstaaij/node-git-describe) contains none; its README has no license
section either.

Canonical MIT text, the license declared in the package's package.json, retrieved via
`gh api licenses/mit`. The copyright holder is the `author` field of that same package.json
("Tim van der Staaij"); no year is stated anywhere upstream, so none is asserted here.
