chore(deps): bump rails from 5.2.2.1 to 6.0.1 in /rails

[dependabot-preview]

Bumps rails from 5.2.2.1 to 6.0.1.

Release notes

Sourced from rails's releases.

6.0.1

Active Support

• ActiveSupport::SafeBuffer supports Enumerator methods.

  Shugo Maeda

• The Redis cache store fails gracefully when the server returns a "max number of clients reached" error.

  Brandon Medenwald

• Fixed that mutating a value returned by a memory cache store would unexpectedly change the cached value.

  Jonathan Hyman

• The default inflectors in zeitwerk mode support overrides:

  # config/initializers/zeitwerk.rb
  Rails.autoloaders.each do |autoloader|
    autoloader.inflector.inflect(
      "html_parser" => "HTMLParser",
      "ssl_error"   => "SSLError"
    )
  end

  That way, you can tweak how individual basenames are inflected without touching Active Support inflection rules, which are global. These inflectors fallback to String#camelize, so existing inflection rules are still taken into account for non-overridden basenames.

  Please, check the autoloading guide for zeitwerk mode if you prefer not to depend on String#camelize at all.

  Xavier Noria

• Improve Range#===, Range#include?, and Range#cover? to work with beginless (startless) and endless range targets.

  Allen Hsu, Andrew Hodgkinson

• Don't use Process#clock_gettime(CLOCK_PROCESS_CPUTIME_ID) on Solaris

  Iain Beeston

Active Model

• No changes.
