Code Review

This pull request updates the default version of Chromium and ChromeDriver from 151.0.7873.0 to 151.0.7874.0. The changes include updating the version mappings, URLs, and integrity hashes in the bzl and json configuration files under the rules_browsers private versions directory, and updating the corresponding MODULE.bazel.lock files across multiple modules. Since there are no review comments, I have no feedback to provide.
