Ensure version numbers are bumped for benchmark and local-linker.

Due to this repos somewhat odd setup (we publish from within
`dist/@glimmer/<PACKAGE_NAME>` instead of the location actually
referenced by the `workspaces` configuration in `package.json`) we have
to maintain the list of `package.json`s to update as special
`release-it-yarn-workspaces` configuration (normally it would just infer
everything from `workspaces` setting).
