See watson/ci-info#95 for more context on
achieving parity between these two modules.

This changes npm to use `ci-info` instead of `@npmcli/ci-detect`.
Everything that npm currently flags as a CI environment should still be
doing so, so there is no breaking change there.

There is going to be a subtle difference in the `ci-name` config, which
nothing in npm currently looks at anyways, as well as the ci name that
shows up in the default `user-agent` string.  Some providers will be
slightly different (i.e. circle-ci vs circleci and cirrus vs cirrus-ci)
