an update to our CLI tool to make sure that the correct llms-full.txt is fetched based on the user's framework
Currently, the create-jazz-app CLI tool fetches an llms-full.txt file which contains a summary of all the content contained in the docs, regardless of framework.
However, since my previous PR got merged, we're generating framework-specific llms-full.txt files, which will be a) smaller and b) less confusing for LLMs, so now, only the appropriate llms-full.txt gets pulled.
