The `ng-dev` tool no longer supports regular expressions for the labels.
This means that we now always require the merge ready label. It can be
used together with the `merge-assistance` label (both labels have been
commonly aplied anyway for our other filters).
The pullapprove label should not indicate merge assistance/a caretaker
note because it does not require additional action by the caretaker.

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`).
