scripting: Disable an eslint warning

Calling await in a loop means the asynchronous operations are
run sequentially instead of in-parallel. Usually that's not
what's wanted, so eslint has a rule to warn about this.

However here we use async/await to handle control back to the
mainloop between steps, so running operations sequentially is
actually intended.
