Bumps rails from 5.2.2 to 5.2.2.1. This update includes security fixes.
Vulnerabilities fixed

> **Critical severity vulnerability that affects actionview**
> # Denial of Service Vulnerability in Action View
>
> Impact
> ------
> Specially crafted accept headers can cause the Action View template location
> code to consume 100% CPU, causing the server unable to process requests. This
> impacts all Rails applications that render views.
>
> All users running an affected release should either upgrade or use one of the

> Releases
> --------
> The 6.0.0.beta3, 5.2.2.1, 5.1.6.2, 5.0.7.2, and 4.2.11.1 releases are

> Workarounds

> This vulnerability can be mitigated by wrapping `render` calls with

> **High severity vulnerability that affects actionview**
> # File Content Disclosure in Action View
>
> Impact
> ------
> There is a possible file content disclosure vulnerability in Action View.
> Specially crafted accept headers in combination with calls to `render file:`
> can cause arbitrary files on the target server to be rendered, disclosing the
> file contents.
>
> The impact is limited to calls to `render` which render file contents without

> ```
> class UserController < ApplicationController
> def index
> render file: "#{Rails.root}/some/file"
> end

> Impact
