We need to switch the package builder to ESM or TS, like we did
in the components repo, but for now until we can, the release script
should work by loading the package builder CJS through the dynamic
import expression.

With the new ESM version of `ng-dev`, the TypeScript config loading
cannot happen automatically because `ts-node` cannot hook into the
Node ESM module resolution at runtime. To fix this `ng-dev` is now
loading a plain `.ng-dev/config.mjs` and the runtime just needs to be
configured accordingly, i.e. running `ng-dev` with `ts-node` so that
the ESM loader can be wired up before Node's runtime starts (using e.g.
`node --loader`).
