Release google-cloud-translate 2.0.0 (#4286)

#### ⚠ BREAKING CHANGES

* Add Translate V3 client
  * Update google-cloud-translate to contain a generated v3 client
    as well as the legacy hand-written v2 client.
  * The following methods now return an instance of
    Google::Cloud::Translate::V3::TranslationServiceClient:
    * Google::Cloud#translate
    * Google::Cloud.translate
    * Google::Cloud::Translate.new
  * To use the legacy v2 client specify the version when creating:
    * v2_client = Google::Cloud::Translate.new version: :v2

#### Features

* Add Translate V3 client
  * The v3 client includes several new features and updates:
  * Glossaries - Create a custom dictionary to correctly and
    consistently translate terms that are customer-specific.
  * Batch requests - Make an asynchronous request to translate
    large amounts of text.
  * AutoML models - Cloud Translation adds support for translating
    text with custom models that you create using AutoML Translation.
  * Labels - The Cloud Translation API supports adding user-defined
    labels (key-value pairs) to requests.
* Now requires Ruby 2.4 or later.
