package:hooks_runner v0.22.0

• Bump package:hooks to 0.20.0.
• Enable passing metadata from link hooks of a package to the link hooks in
  depending packages, by fixing the link hook execution order. This brings an
  order in which the link hooks are run - reverse to the build hook run order.
  Starting at the application link hook, then it's dependencies, and so on. This
  enables us to pass information from on link hook to another as
  MetadataAssets - but also means that now link hooks must be invoked,
  regardless of whether assets are sent to the from a build hook.
