[BUG] using Gemini LLM doesn't work in main branch

[mottolini]

Describe the bug
After you insert your key in the configuration of both the LLM and the Embedder, whenever you try to get a response you receive the error:

Invalid argument provided to Gemini: 400 * GenerateContentRequest.generation_config.stop_sequences: the number of stop_sequences must not exceed 5.

To Reproduce
This happens on branch main, commit c79272b.
It appears to be already fixed on branch develop, commit 3860a48

@mottolini can you confirm it works with VPN in develop?
Gave more info in #827

@mottolini can you check if the proble is still there in Cat 1.6.2?

@mottolini can you check if the proble is still there in Cat 1.6.2?

It is even worse because currently you cannot set a Gemini API key on v 1.6.2
