docs: Add how-to guide for aligning LLM-as-Judge (#2348)

## Issue Link / Problem Description
Adds documentation and examples for aligning LLM-as-Judge evaluators
with human expert judgments. This addresses a common challenge where LLM
judges may not align well with human evaluations, leading to unreliable
automated assessments.

## Changes Made
- Add comprehensive how-to guide:
`docs/howtos/applications/align-llm-as-judge.md`
- Step-by-step instructions for measuring and improving judge alignment
- Add complete evaluation example:
`examples/ragas_examples/judge_alignment/`
- `evals.py`: Baseline and improved judge metrics with alignment
measurement
  - `__init__.py`: Module initialization with main entry points
- Documentation covers:
  - Why judge alignment matters
  - Dataset structure and loading
  - Defining judge and alignment metrics
  - Running baseline evaluations
  - Iterating on judge prompts to improve alignment

## Testing
### How to Test
- [x] Manual testing steps:
1. Run baseline evaluation: `uv run python -m
ragas_examples.judge_alignment`
  2. Verify alignment metrics are calculated correctly
  3. Build docs locally: `make serve-docs` and navigate to the new guide
