I'm fine with this, but I wouldn't declare this a fix. This should instead be ci.

At first glance "build" or "chore" sounds more correct according to https://github.com/angular/angular/blob/22b96b9/CONTRIBUTING.md#type.
Because we not only change the CI, but the actual binary that is build and ship.
But I let you make the final call

[Techassi]

Yes, build also works.
