Broken links for "Use case code examples" from "Building Generative AI Applications Using Amazon Bedrock" Amazon Skill Builder course

After some restructuring of the content of this repository, several links to the course use cases became broken, which makes it impossible to easily access the examples.

When restructuring the repository content, the course should be updated or some guardrails should be implemented to avoid this problem (like a Github Action that checks whether any of the repository links are used within Amazon Skill Builder content).

Current course links (that are all broken):

Start by checking the eight broken GitHub URLs listed in the issue and comparing them with the repository's current structure. Determine whether the course links can be updated or whether a repository-link validation guardrail is feasible; done means the course examples are reachable or broken links are detected before restructuring is released.
