Add routes for each example in the component pages

[dlabaj]

Description

Add routes to each of the examples in the component pages. This is needed for a11y testing, visual regression testing, and full page demos. Possibly used for integration testing as well.

To Do

• Keep in mind the api and how routes.js works in the current documentation framework. This api is used by other tooling (e.g. the screen shot tool - backstop.js). We may have to up the documentation, and we do not want to break the other tooling.
• Code to generate the examples into full page demos and routes have been added
• Verify a11y testing works with Astro
• Verify visual regression testing works with Astro
• Integrated into CI / CD
• Unit tests have been added
