Update to the latest package:yaml

Expand the range allowed by the dep from `package:analyzer`.

Switch dependencies to `any` for the packages which are `publish_to:
none`. The actual constraints aren't useful in these packages since they
are always pinned exactly by DEPS and so we can't trust they are kept up
to date.
