fix: correct disable_thoughts logic in system prompt

[Aoi-cn]

I found that the logic in moatless-tools/moatless/completion/react.py:44 - 52 is conflicting with the check logic in moatless-tools/moatless/completion/react.py:146 - 151

# moatless-tools/moatless/completion/react.py:44 - 52
system_prompt += dedent(f"""\n# Response format

Use the following format:
{'' if not self.disable_thoughts else '''            # Meaning that use prompt with 'thought' when `disable_thoughts` is `True` 
Thought: You should always think about what to do'''}
Action: The action to take followed by the input arguments based on the schema below

Use one of the following actions and provide input arguments matching the schema.
                            
{input_schemas}

Important: Do not include multiple{'' if self.disable_thoughts else ' Thought-'} Action blocks. Do not include code blocks or additional text outside of this format.
""")

# moatless-tools/moatless/completion/react.py:146 - 151

if not self.disable_thoughts and thought_count < 1:   # Meaning that there needs a 'Thought' when `disable_thoughts` is `True`
    raise ValueError("The response is incorrect, it should start with 'Thought:'")
if action_count < 1:
    raise ValueError("Response must have one 'Action:' section")

if not self.disable_thoughts:
    # Find the starting lines for each section
    thought_line = next((i for i, line in enumerate(lines) if line.startswith("Thought:")), -1)
    action_line = next((i for i, line in enumerate(lines) if line.startswith("Action:")), -1)

    # Check if sections are in correct order
    if not (thought_line < action_line):
        raise ValueError(
            "Your response is incorrect. The Thought section must come before the Action section. Please try the same request again with the correct format."
        )

After comparing, I think the logic in 146-151 might be the right one, so I took the liberty to modify the above logic, I don't know if the modification is correct.
