Stop using Mocha

Instead of creating new arrays for `uniq` and `map` we can instead modify the array in place.

This was introduced at 24f6bf0d.

Add database configuration to disable advisory locks.

This patch corrects a duplicate method name introduced in #33635.

Also fixes typo in method names.

[ci skip] Add ImageMagick to Brewfile

In order to run ActiveStorage's tests successfully, you need imagemagick

Add usage of procs without arguments to callbacks guide

Make `rake routes` deprecate before deleting

Improve Active Job test helpers

The `Relation::Merger` has a problem that order values would be merged
as nested array.

That was caused an issue #33664 since if array value is passed to
`order` and first element in the array includes `?`, the array is
regarded as a prepared statement and bind variables.

https://api.rubyonrails.org/classes/ActiveRecord/Sanitization/ClassMethods.html#method-i-sanitize_sql_for_order

Just merging that as splat args like other values would fix the issue.

Fixes #33664.

Fix `rails routes -c` for controller name consists of multiple word.

Improve tests for ActiveRecord::ConnectionAdapters::ConnectionPool co…

Example:
```
def test_assert_performed_with
  MyJob.perform_later(1,2,3)

  perform_enqueued_jobs

  assert_performed_with(job: MyJob, args: [1,2,3], queue: 'high')
end
```

Follow up #33626.

Execution of `assert_performed_jobs`, and `assert_no_performed_jobs`
without a block should respect passed `:except`, `:only`, and `:queue` options.

Note that it removes changelog entry of #33265 since the entry in this commits
includes that too.

If the `:queue` option is specified, then only the job(s) enqueued to a specific
queue will not be performed.

Example:
```
def test_assert_no_performed_jobs_with_queue_option
  assert_no_performed_jobs queue: :some_queue do
    HelloJob.set(queue: :other_queue).perform_later("jeremy")
  end
end
```

If the `:queue` option is specified, then only the job(s) enqueued to a specific
queue will be performed.

Example:
```
def test_assert_performed_jobs_with_queue_option
  assert_performed_jobs 1, queue: :some_queue do
    HelloJob.set(queue: :some_queue).perform_later("jeremy")
    HelloJob.set(queue: :other_queue).perform_later("bogdan")
  end
end
```
