Remove code climate github action

[rodrigoaguilera]

In my latest PR #66 I changed the action that was publishing the code coverage report because I thought the env variable CC_TEST_REPORTER_ID was somehow added to the CI builds of the master branch but I apparently is not.

Should we remove until someone is willing to configure code climate again?

I think that CodeClimate was never really setup for this project/repository and was just here as part of forking the original project. I'll take a look at it right away :)

CodeClimate is now setup: https://codeclimate.com/github/beluga-php/docker-php
I've re-run the action but there is still some issue when prefer-lowest combination is used. I don't have enough bandwidth right now to look at it, but I'll do later.

Here is an attempt to fix that #68
