docs: update release docs (ethereum#1606)

- not every release is a prerelease, now, so update version guidance
- add ethportal-api release instructions
- don't rebase local master before tagging release

If you have commits on your local master branch, rebasing would tag them
into the release, bypassing the standard PR process.

 Make sure that version follows [semver](https://semver.org/) rules e.g (`0.2.0-alpha.3`).

 We use automated github release workflow to create a new release.
 This will create a new release draft with the new tag and will build all the binaries and attach them to the release. 
 
 1. Checkout and rebase local master to upstream
 ```bash
 git checkout master
-git pull --rebase upstream master
+git pull --ff-only upstream master
 ```
 2. Create a new git tag with the chosen version, for example:
 ```bash
