WIP: Update how release script would be doing
Clarifying:
- It would clone fresh CE and/or EE, so it's clear we're not doing this in CE nor EE.
- State that it's just roughly doing those steps, so we should not do them manually as the script could also do other things as we update the script.
- Specify the remotes, so readers are aware that those remotes should be synchronized (and we might make the script to do so in the future)
