Remove blog slugs and add redirects instead for compatibility with docs-chatbot link parsing.

Currently, if you add a custom slug to a blog, the docs-chatbot (i.e. Ask Defang) will provide an incorrect link to that blog in its list of references because the link is auto-generated based on the file name. For example, if the file name in the repo is 2025-06-16-crew-ai-sample.md , the docs-chatbot will generate the link using the formula that changes dates to slashes and uses the exact file name, such as 2025/06/16-crew-ai-sample. If you use a slug such as rag-agents-crew-ai-sample, then the docs-chatbot will not be able to point to that link ending because it only knows the auto-generated link.

I would suggest using redirects in the docusaurus.config.js file to redirect a user to a particular link as an alternative to slugs for better compatibility with the chatbot in its current state.
