fixes: #18

We have enabled branch protection with status checks, but on each individual Ruby version. it's better to have a step that depends on the previous steps. So an example is here:

https://github.com/voxpupuli/gha-puppet/blob/ccce1fb2a2df9a0b619e522a3f516e7c8a6d20d6/.github/workflows/basic.yml#L97-L103

It depends on the matrix (needs: unit). So that you can safely make a required check and then you can change the test matrix within a PR without changing the required checks in GH every time you do.

@ekohl : the project branch protection expects ruby 2.4, 2.5 and 2.6. is this something i can change in code or do i have to go the branch protection rules and update it there? unclear what is expected to be done here. 😵‍💫

sry, i'm not a gha pro.

You need to be a GH admin (at least on the repo). I've just modified it, but what I did was:

• Go to Settings
• Go to Branches
• Edit the master branch protection
• Change Require status checks to pass before merging to be Test suite (and dropped all individual checks)
• Save

Now you can see that it only requires the Test / Test suite check.

i am able to go there, but was not sure if i'm supposed/allowed to do it. sry, still a bit insecure what i can do, dont want to break something,
