Github actions integration doesn't work

Using the exact example from the README file, I receive:

Prepare all required actions
Getting action download info
Error: Unable to resolve action `akaihola/darker@1.4.0`, unable to find version `1.4.0`

I've tried to change the version 1.3.2 (and some additional ones) and got:

Download action repository 'actions/checkout@v2' (SHA:ec3a7ce113134d7a93b817d10a8272cb61118579)
Download action repository 'akaihola/darker@1.3.2' (SHA:67ca4ae1bdb9e7f832f7bb932a683496e70c4faa)
Error: Can't find 'action.yml', 'action.yaml' or 'Dockerfile' under '/home/runner/work/_actions/akaihola/darker/1.3.2'. Did you forget to run actions/checkout before running your local action?

Version 1.4.0 hasn't yet been released, so that's not supposed to work.

Version 1.3.2 didn't have GitHub Actions support yet.

So the only thing that could work right now is akaihola/darker@master.

Sorry for the confusion, I was anticipating to release 1.4.0 very soon after merging this feature, but it got delayed by life. So this will be fixed once 1.4.0 is released.
