Fix: Improve Vale repetition rule to exclude code blocks and fix typo in docs (#5162)

This pull request improves the documentation style checks and fixes a small typo.

Changes:

Added a custom Vale rule at .github/styles/Kedro/Repetition.yml to avoid flagging repeated words inside code blocks and inline code (e.g., kedro.runner.runner, kedro.pipeline.pipeline). This helps reduce false positives while still catching repetition in regular text.

Fixed a typo in docs/develop/automated_testing.md (“he option” → “The option”).
