chore(review): point CodeRabbit at dev and the moved ESLint config

[alexeyv]

Two fixes to .coderabbit.yaml.

• base_branches listed main, which is the default branch and needs no listing, while every PR now targets dev. CodeRabbit has not reviewed the recent PRs into dev; this should bring it back.
• The path filter still excluded eslint.config.mjs at the root. It moved to docs-site/ in build: move the Node toolchain into docs-site #2834, as greptile.json already reflects.

Greptile Summary

Updates CodeRabbit configuration to restore automatic reviews for development PRs and track the relocated ESLint configuration.

• Adds dev to the explicitly reviewed base branches while the default main branch remains implicitly covered.
• Replaces the stale root ESLint-config exclusion with docs-site/eslint.config.mjs.

Confidence Score: 5/5

The PR appears safe to merge with no actionable issues identified.

The branch filter matches the repository’s development workflow without removing default-branch coverage, and the updated path filter resolves to the relocated ESLint configuration.
