`Rails/I18nLocaleTexts` false negative when using alert or notice in `redirect_back_or_to`

[ydakuka]

It seems that the Rails/I18nLocaleTexts cop does not consistently detect inline locale strings in controller redirects.

In the following example, the cop correctly flags the notice message, but does not flag the alert message, even though both are inline strings and should be treated the same:

Steps to reproduce the problem

Expected behavior

Both alert and notice (and any other flash message keys) with inline strings should be flagged by Rails/I18nLocaleTexts.

Actual behavior

def update
  unless @daily_revenue.unpaid?
    redirect_back_or_to campaign_managers_daily_revenues_path,
                        alert: 'Cannot edit non-unpaid records'
    return
  end

  # ...
end
