Switch to GitHub Actions CI.

[XhmikosR]

This is just a basic setup, I haven't backported the branch limitations.

@kristerkari: first you will need to enable GH Actions: https://github.com/features/actions

EDIT: it seems there's a bug and on Windows they use Node.js 8.10.0 which doesn't have npm ci command. actions/setup-node#27

@kristerkari what's your take on this?

You can see this on my fork https://github.com/XhmikosR/stylelint-config-recommended-scss/commit/6eee6b7c2761e75c9d01dfb2c57fd6a17a786823/checks?check_suite_id=245911495

I haven't used Github's CI before, so I think that I need to look into it a bit before switching to use it.

If it has the same features as the other CI systems, then it's ok for me.

[XhmikosR]

It's actually better IMO so far. You can test fast, cross-platform, and without another 3rd-party service.

It does lack some features like caching, but those will be fixed eventually.

stylelint switched a couple of weeks ago, pretty happy with it

You can see the final PR we merged adding them here:

stylelint/stylelint#4285

[kristerkari]

Thanks for taking the time to do the changes!

[XhmikosR]

@kristerkari you haven't registered for Actions yet :/

[kristerkari]

I just did a few minutes ago

[XhmikosR]

Weird, I don't see them enabled yet...

[XhmikosR]

Either way, you should remove Travis and AppVeyor from apps/integrations/hooks when Actions is enabled.

[kristerkari]

I'm currently removing AppVeoyr and Travis

[kristerkari]

Weird, I don't see them enabled yet...

It seems that there is some kind of a waiting list since it's a Beta feature. I guess we'll just have to wait a bit for it to be enabled.

[XhmikosR]

No worries, you can revert this and make a new PR to merge when it's enabled.

[kristerkari]

Let's see how long it takes, if it's quick, then I don't think that there is any need to revert the changes.
