Unify "Link/LinkTo::Standalone" component (04)

[didoo]

📌 Summary

Now that we have a single interactive element that handles both the normal <a> links and the <LinkTo> links, there's no reason why we should keep separate the "standalone" link in two distinct components, we can use the same method (@href vs @route) to detect which one is needed, using the underlying Hds::Interactive component that does all the work for us.

This will also simplify the adoption of the component in the consumers codebases, and its documentation.

Notice: even if under the hood it's using the Hds::Interactive component, this Hds::Link::Standalone can’t be used as a button, because there’s an assertion thrown if nor @route nor @href are passed as arguments.

🛠️ Detailed description

In this PR I have:

• removed the LinkTo::Standalone component from the codebase
  • component
  • documentation
  • tests (percy + integration)
• updated the Link::Standalone to use the new interactive generic component
  • in this way it serves both the old Link::Standalone and LinkTo::Standalone use cases
• unified the documentation page - page preview
• updated the integration tests

@alex-ju @MelSumner @Dhaulagiri can you review also this one? thanks

[alex-ju]

Assuming the 'Interactive' component makes its way in, I agree these two shall be merged. Couldn't spot anything off in the code.

I think we should consider not removing components until we're sure of the unified interactive component approach. WDYT?

OK for me. In any case, this PR is branched from the interactive branch, and will be merged back into it, so they go hand in hand, so there's no risk of releasing one without the other. So I am merging in the main feature branch, and it will stay there until we are OK with the global changes.
