docs: Fix missing --gpu all flag in Docker run commands (#2026)

adding the --gpu all flag to Docker run commands
for meta-reference-gpu distributions ensures models are loaded into GPU
instead of CPU.

Remove docs for meta-reference-quantized-gpu
The distribution was removed in #1887
but these files were left behind.


Fixes: #1798

# What does this PR do?
Fixes doc to add --gpu all command to docker run

Closes #1798

## Test Plan
[Describe the tests you ran to verify your changes with result
summaries. *Provide clear instructions so the plan can be easily
re-executed.*]

-# Meta Reference Quantized Distribution
-
-```{toctree}
-:maxdepth: 2
-:hidden:
-
-self
-```
-
-The `llamastack/distribution-meta-reference-quantized-gpu` distribution consists of the following provider configurations:
-
-| API | Provider(s) |
-|-----|-------------|
-| agents | `inline::meta-reference` |
-| datasetio | `remote::huggingface`, `inline::localfs` |
-| eval | `inline::meta-reference` |
-| inference | `inline::meta-reference-quantized` |
-| safety | `inline::llama-guard` |
-| scoring | `inline::basic`, `inline::llm-as-judge`, `inline::braintrust` |
-| telemetry | `inline::meta-reference` |
-| tool_runtime | `remote::brave-search`, `remote::tavily-search`, `inline::code-interpreter`, `inline::rag-runtime`, `remote::model-context-protocol` |
-| vector_io | `inline::faiss`, `remote::chromadb`, `remote::pgvector` |
-
-
-The only difference vs. the `meta-reference-gpu` distribution is that it has support for more efficient inference -- with fp8, int4 quantization, etc.
-
-Note that you need access to nvidia GPUs to run this distribution. This distribution is not compatible with CPU-only machines or machines with AMD GPUs.
-
-### Environment Variables
-
-The following environment variables can be configured:
-
-- `LLAMA_STACK_PORT`: Port for the Llama Stack distribution server (default: `8321`)
-- `INFERENCE_MODEL`: Inference model loaded into the Meta Reference server (default: `meta-llama/Llama-3.2-3B-Instruct`)
-- `INFERENCE_CHECKPOINT_DIR`: Directory containing the Meta Reference model checkpoint (default: `null`)
-
-
-## Prerequisite: Downloading Models
-
-Please use `llama model list --downloaded` to check that you have llama model checkpoints downloaded in `~/.llama` before proceeding. See [installation guide](https://llama-stack.readthedocs.io/en/latest/references/llama_cli_reference/download_models.html) here to download the models. Run `llama model list` to see the available models to download, and `llama model download` to download the checkpoints.

-## Running the Distribution
-
-You can do this via Conda (build code) or Docker which has a pre-built image.
-
-### Via Docker
-
-This method allows you to get started quickly without having to build the distribution code.
-
-```bash
-LLAMA_STACK_PORT=8321
-docker run \
-  -it \
-  --pull always \
-  -p $LLAMA_STACK_PORT:$LLAMA_STACK_PORT \
-  -v ~/.llama:/root/.llama \
-  llamastack/distribution-meta-reference-quantized-gpu \
-  --port $LLAMA_STACK_PORT \
-  --env INFERENCE_MODEL=meta-llama/Llama-3.2-3B-Instruct
-```
-
-If you are using Llama Stack Safety / Shield APIs, use:
-
-```bash
-docker run \
-  -it \
-  --pull always \
-  -p $LLAMA_STACK_PORT:$LLAMA_STACK_PORT \
-  -v ~/.llama:/root/.llama \
-  llamastack/distribution-meta-reference-quantized-gpu \
-  --port $LLAMA_STACK_PORT \
-  --env INFERENCE_MODEL=meta-llama/Llama-3.2-3B-Instruct \
-  --env SAFETY_MODEL=meta-llama/Llama-Guard-3-1B
-```
-
-### Via Conda
-
-Make sure you have done `uv pip install llama-stack` and have the Llama Stack CLI available.
-
-```bash
-llama stack build --template meta-reference-quantized-gpu --image-type conda
-llama stack run distributions/meta-reference-quantized-gpu/run.yaml \
-  --port $LLAMA_STACK_PORT \
-  --env INFERENCE_MODEL=meta-llama/Llama-3.2-3B-Instruct
-```
-
-If you are using Llama Stack Safety / Shield APIs, use:
-
-```bash
-llama stack run distributions/meta-reference-quantized-gpu/run-with-safety.yaml \
-  --port $LLAMA_STACK_PORT \
-  --env INFERENCE_MODEL=meta-llama/Llama-3.2-3B-Instruct \
-  --env SAFETY_MODEL=meta-llama/Llama-Guard-3-1B
-```
