chore(deps): remove deprecated @angular/animations

Angular deprecated the package in favour of `animate.enter` and
`animate.leave`. Nothing in the app or in Angular Material imports it,
and `@angular/platform-browser` only lists it as an optional peer, so it
is dropped instead of migrated. Clears the Renovate dashboard warning in #56.
