workflows : remove nocleanup arg for check-requirements.sh (#5826)

Reduces peak tmpfs usage and should prevent the check from failing from
running out of space.

Fixes the 'No space left on device' issue mentioned in #5703.

-## Convert
-Example for llama model
-```bash
-# For llama7b and llama2 models
-python convert.py models/llama-7b/ --awq-path awq_cache/llama-7b-w4-g128.pt --outfile models/llama_7b_fp16.gguf

-./quantize models/llama_7b_fp16.gguf models/llama_7b_q4_0.gguf q4_0
-```

-```bash
-# For all models.
-./build/bin/main -m models/llama_7b_q4_0.gguf -n 128 --prompt "Once upon a time"
-```
-
-## Benchmark
-The perplexity measurements in table above are done against the `wikitext2` test dataset (https://paperswithcode.com/dataset/wikitext-2), with context length of 512.

-
-## Results
-Results are run on OpenBLAS (CPU) and CuBLAS (GPU) for fair comparison
-We use three types of llamacpp quantization methods to work with our version, including q4_0, q4_1, and q2_k

 ### API like OAI
 
-API example using Python Flask: [api_like_OAI.py](api_like_OAI.py)
-This example must be used with server.cpp
-
-```sh
-python api_like_OAI.py
-```
-
-After running the API server, you can use it in Python by setting the API base URL.
-
-```python
-openai.api_base = "http://<Your api-server IP>:port"
-```
-
-Then you can utilize llama.cpp as an OpenAI's **chat.completion** or **text_completion** API
+The HTTP server supports OAI-like API
