Feat: Use step summary, labeled distinctly

[mchenryc]

This PR changes the "summary" mechanism to post overall results of a workflow to use the new Step Summaries, solving two problems I have run into:

1. Multiple Cucumber tasks (due to job matrix, or other) use the same title on the "summary annotation" so it is difficult to tell from the Workflow summary which results were for which cucumber run
2. The summary annotation has an unnecessary "link to file position"

Instead of a "summary annotation" this adds much same information in a step summary, using the title of the cucumber step, which is displayed nicely in the overall workflow summary page. Because it uses markdown, future changes can make this much more pretty and/or informative.

Note this builds directly off the on the repository cleanup and distribution mechanism in #32. See commit d24a4c2 for actual changes.

Should be good to go. Permissions on GH Actions repos are a nuisance. Thanks for accepting!

@deblockt with this merged, is it worth publishing a 1.9 release?

@mchenryc done sorry for the delay
