message: Small adjustments to the changelog
diff: - Use generated Typescript types via client:codegen [#1016](https://github.com/apollographql/apollo-tooling/pull/1016)
  - Remove default `--tag=current` for some client commands that used it [#1062](https://github.com/apollographql/apollo-tooling/pull/1062)
  - Add missing dependency `@oclif/errors` [#1068](https://github.com/apollographql/apollo-tooling/pull/1068)
  - - The keyword "type" is escaped when generating scala.js via client:codegen [#1066](https://github.com/apollographql/apollo-tooling/pull/1066)
  - Include targetUrl in the output of the `service:check` command [#1072](https://github.com/apollographql/apollo-tooling/pull/1072)
  - Expand the `graphql` peer dependency range of `apollo-graphql` to also include `0.13.x` and `0.12.x` in addition to `14.x`, since the `apollo-graphql` package is relied upon by `apollo-server-core` which specifies those requirements itself.
