Documentation Bug: Non-LLM metrics inheritance described incorrectly

[AlanPonnachan]

[x] I have checked the documentation and related resources and couldn't resolve my bug.

Describe the bug
In the documentation section Types of Metrics in Ragas, there is a mistake in the description of Non-LLM-based metrics.

It currently says:

All LLM based metrics in ragas are inherited from Metric class.

This is incorrect. Based on the codebase and usage:

• LLM-based metrics inherit from MetricWithLLM
• Non-LLM-based metrics inherit from Metric

So the line should read:

All Non-LLM-based metrics in ragas are inherited from Metric class.

Ragas version:
N/A (documentation bug)

Python version:
N/A

Code to Reproduce
Not applicable (documentation bug).

Error trace
Not applicable.

Expected behavior
The documentation should correctly describe that Non-LLM-based metrics inherit from Metric, while LLM-based metrics inherit from MetricWithLLM.

Additional context
This may cause confusion for users implementing their own metrics.

I’d be happy to raise a PR to fix this documentation mistake in the Metrics Overview page. Please let me know if that works and I can go ahead with the change.
