fix: Set dependabot ignore for major updates to eslint

[swadeley]

Description

Hold Eslint version to 9.x because with ESLint 10, eslint-plugin-react breaks for every file
 (e.g. src/App.tsx) because of the context.getFilename API change, not only for Playwright tests.

How to test the PR

Tests pass
