The MIT notice carried "Copyright 2020-2021" with no holder, which is the one
line the licence needs to be attributable: the permission grant refers back to
"the above copyright notice", and a notice naming nobody is weak to point at
when the project is republished without attribution.
Uses the handle the project already publishes as its author in package.json.
The range now starts at 2019, the year of the first commit, and runs to the
current year. The canonical "MIT License" title line is added so automated
licence detection matches the file exactly.
