fix 05 + 07 docs (LLM doc + Shrek doc) for compatibility with v0.1.0

[Joshua-Briggs]

01 - when loading a doc im creating a new instance of rl instead of using the same rl, you might want to check this to make sure its correct. 05 - cannot get the LLM to run with the semantic router 07 - compatibility issues with the encoder, also think the dependency semantic_router[vision] needs updating
