Subject: [PATCH 1/2] Chore: Repro missing built-in rule validation (refs
 #13793)

The bulk of our tests for rule schemas are isolated unit tests of
`ConfigValidator`. This is a single test to be sure we actually run rule
schema validation end-to-end and prevent cases like #13793.

After I run a patch release of `@eslint/eslintrc`, I'll push a second
commit on this branch to bump the dependency version and fix the test.
