fix(gallery): remove unsupported Instella-MoE models

Both GGUF entries select llama-cpp, whose pinned revision does not
recognize instella-moe. Remove the broken install options and document
why they are unavailable until LocalAI ships a compatible backend.

+## Instella-MoE availability
+
+The gallery excludes `instella-moe-16b-a3b-think` and
+`instella-moe-16b-a3b-think-q8` because the packaged llama.cpp backend does not
+support their `instella-moe` architecture. Loading these GGUF files fails with
+`unknown model architecture: 'instella-moe'`.
+
+The entries can return after LocalAI ships a compatible backend. See
+[the compatibility issue](https://github.com/mudler/LocalAI/issues/11681) and
+[upstream llama.cpp support](https://github.com/ggml-org/llama.cpp/pull/26467).
