fix: bump to es2022 support

BREAKING CHANGE: this drops support for eslint@7
Our testing matrix is where we ensure we are working in the environments
we need. The linter is not what should be slowing us down with what
features we write.

Not a blocker but I wanted to point out that node/process-exit-as-throw is currently broken with eslint@8: mysticatea/eslint-plugin-node#301

I think we should manually disable any cases that break because of this with a comment to revisit when that issue is fixed.

Well hopefully process.exit() isn't in any of our hot paths outside of things like the helper bins that ship with things like pacote or arborist. Seems like a good place to double check that the code looks right anyways, and the cli itself is the only process.exit() that we really need to be super prescriptive about.
