Bumps rails from 7.2.2 to 8.1.0.

Release notes

Sourced from rails's releases.

8.1.0

Active Support

• Remove deprecated passing a Time object to Time#since.

  Rafael Mendonça França

• Remove deprecated Benchmark.ms method. It is now defined in the benchmark gem.

  Rafael Mendonça França

• Remove deprecated addition for Time instances with ActiveSupport::TimeWithZone.

  Rafael Mendonça França

• Remove deprecated support for to_time to preserve the system local time. It will now always preserve the receiver timezone.

  Rafael Mendonça França

• Deprecate config.active_support.to_time_preserves_timezone.

  Rafael Mendonça França

• Standardize event name formatting in assert_event_reported error messages.

  The event name in failure messages now uses .inspect (e.g., name: "user.created") to match assert_events_reported and provide type clarity between strings and symbols. This only affects tests that assert on the failure message format itself.

  George Ma

• Fix Enumerable#sole to return the full tuple instead of just the first element of the tuple.

  Olivier Bellone

• Fix parallel tests hanging when worker processes die abruptly.

  Previously, if a worker process was killed (e.g., OOM killed, kill -9) during parallel test execution, the test suite would hang forever waiting for the dead worker.

  Joshua Young

• Add config.active_support.escape_js_separators_in_json.

  Introduce a new framework default to skip escaping LINE SEPARATOR (U+2028) and PARAGRAPH SEPARATOR (U+2029) in JSON.

  Historically these characters were not valid inside JavaScript literal strings but that changed in ECMAScript 2019. As such it's no longer a concern in modern browsers: https://caniuse.com/mdn-javascript_builtins_json_json_superset.
