fix(deps-dev): upgrade typescript-eslint to v8 for ESLint 9 compatibility

ESLint 9 requires typescript-eslint v8+, but the dependabot upgrade only bumped ESLint itself. This adds the necessary typescript-eslint upgrades and yarn resolutions to resolve the incompatibility with @sentry-internal/eslint-config-sdk which depends on v5. Also adds ESLINT_USE_FLAT_CONFIG=false to support legacy .eslintrc.js format.
