docs: update summarization calculation (#1510)

There is mismatch how coeff is used in docs vs actual computation. Related code is in: https://github.com/explodinggradients/ragas/blob/889fe2b9181baf203ca96fa876a54c7d80989767/src/ragas/metrics/_summarization.py#L189 ![Screenshot 2024-10-15 at 17 29 16](https://github.com/user-attachments/assets/3d987aaf-656f-4e10-ba84-1ee0bc2fa44a) Co-authored-by: Jakub Kanitra <[email protected]>

 The final summarization score is then calculated as:
 
 $$
-\text{Summarization Score} = \text{QA score}*\text{coeff} + \\
-\text{conciseness score}*\text{(1-coeff)}
+\text{Summarization Score} = \text{QA score}*\text{(1-coeff)} + \\
