Out of Date README.md

[mchisolm0]

The README currently references node 14 as LTS and 16 as current.
After installing nvm, using the command nvm install 16(for current) or nvm install 14(for LTS)

This sentence should be updated to 20 and 22, respectively. The sentence describing the nvm command also needs to be updated.
After installing nvm, using the command nvm install 22(for current) or nvm install 20(for LTS)

I will happily create a PR if that would be helpful.
