DEV: Repair RSpec full_cause_backtrace under bin/turbo_rspec (#26087)
This commit fixes two issues:
1. The wrong exception was being printed as the 'cause' in turbo_rspec output. This was happening because RSpec [expects exceptions to be subclasses of `Exception`](d6e320dc11/lib/rspec/core/formatters/exception_presenter.rb (L102)). This commit resolves the issue by replacing the `FakeException` `Struct` with a subclass of `Exception`.
2. The `full_cause_backtrace` option we set in `rails_helper.rb` does not carry through to the RSpec formatters running in the turbo_rspec reporter process. To fix that, this commit duplicates the necessary config in `lib/turbo_tests.rb`.
Example before - note that the cause is a duplicate of the original exception, and only has three lines of backtrace:
```
Failure/Error: raise capybara_timeout_error
CapybaraTimeoutExtension::CapybaraTimedOut:
This spec passed, but capybara waited for the full wait duration (4s) at least once. This will slow down the test suite. Beware of negating the result of selenium's RSpec matchers.

After - note correct causing exception, and the full backtrace 🎉
