DOC: Improve manual release instructions

In the last release (5.2.2), the manual release needed some extra commands that are described below:

- Before `yarn run build` command, if there is no `tsc` (`typescript`) installed it will fail. Probably it should include a `yarn install` command before the building command;
- Before `npm publish out.tgz` maybe would be good to comment to login into the `npm` account using `npm login`.
