How can I remove/reduce the safety options?

### Description of the bug:

My python code looks like this:

```
response = await model.generate_content_async(
prompt,
generation_config={
'temperature': 0.0, 'max_output_tokens': expectedOutputTokens
},
safety_settings={
"HARM_CATEGORY_DANGEROUS": "block_none",
"HARM_CATEGORY_HARASSMENT": "block_none",
"HARM_CATEGORY_HATE_SPEECH": "block_none",
"HARM_CATEGORY_SEXUAL": "block_none"
})
```
It produces internal errors (500) when I try to specify `safety_settings` as above. Is this not the right way? I'm trying to reduce the number of errors I get due to safety. Thanks!

### Actual vs expected behavior:

Would expect this either to fail early with a message telling me what's wrong with my arguments, or for it to work as expected, while producing fewer errors of the sort "response blocked because of safety"

### Any other information you'd like to share?
