Drop support for Node.js 12

[SergeAstapov]

Node.js 14 is currently in Maintenance LTS mode and slated for End Of Life (EOL) on 2023-04-30 (end of this month).

The title is misleading. I thought you were dropping Node 14, you meant dropping 12 in favor of 14 :)
Might want to update the title to make it clearer

What about https://github.com/miragejs/ember-cli-mirage/blob/master/.github/workflows/deploy.yml#L14
While its in the Github actions only really, should prob be consistant

thanks for noticing @cah-briangantzler! Of course meant dropping support for 12.x

gears in my head were spinning around about "making 14 min supported version" but hands wring commit message about dropping support for 12
