chore: update license years

* Updated supported Node.js versions

Dropped support for 14 and 16 in favor of the current LTS versions 18
and 20.

* Updated Node.js dependencies

Bumped nearly all dependencies to the latest. The exception being
`node-fetch` which made the jump to using ESM which is still causing
folks a lot of grief.

* Shored code coverage back up to 100%

Had some remnants from when this library did sanity checks pre-flight to
the API that required additional tests to cover them, or just adjusting
the argument defaults.

* Removed the "build" badge from the README

Seems there were some gotchas with that badge that makes it kind of a
pain, as it has to be hard coded a certain way. I messed with it and
couldn't get it working, seems like more trouble than it's worth.

Further details: https://github.com/badges/shields/issues/8671

* Added .nvmrc file

Pretty self explanatory.

* Bumped version number

Lucky number 7, y'all!
