Add a globe icon to workflow steps that links to the GitHub.com specific step

[KetchupOnMyKetchup]

Closes #139

Issue:

• Users with hundreds of steps would like an easier way to get to the steps.
• User request "I wish the tree nodes for individual steps had a View logs icon just like the nodes for jobs.
• Users want some action to happen when they click on steps.
• We used to have a way to jump to the place in the steps but that was problematic and removed - b2380f0. We wanted to try to show just the step logs specifically in VS Code, but that solution would require better API support because currently there is no way to exactly correlate step names.

Fixes:

• Add a globe icon (indicating an external site) which links to the specific step.
• Change tooltip text from "View logs" to be more specific "View job logs" and "View step logs"

Demo:
