yamllint is now installed by default on GitHub actions virtual environments

See actions/runner-images#1142 (comment)

and adrienverge/yamllint#300

You probably don't need a custom Docket image anymore as yamllint already is installed by default 🤷

@yvele NICE, I'll check it soon. If all is good, this action could potentially be converted to composite action and basically just serve as command line builder for running yamllint. On other hand docker image is good for use in self-hosted runners (though, one could argue that it's easier to preinstall software on self-hosted runners than GitHub provided ones)

Doh, the version deployed is 1.10.0 which is a bit old and doesn't support some options, like -format and looks like it doesn't read .yamllint config by default. Investigation continues ...

I think it is too unpredictable and somewhat disruptive to use pre-installed (outdated) yamllint. I'll create a composite branch have the action use pre-installed yamllint but not include in release, at least not yet.

Hey @ibiqlik it's fixed directly within GitHub Actions see actions/runner-images#1657 (comment) and now install the lastest yamllint version 😉

That's great news @yvele. I'm reopening the issue and will give it another take at composite action.
