Fix the issues reported by phpcs

Added patch for fix coding standards .

I have reviewed patch #2. And it seems as per coding standards. Thank you.

I am reviewing the patch in comment #2.

+   * @param string $plugin_id
+   *   The plugin_id parameter.
+   * @param mixed $plugin_definition
+   *   The Plugin_definition parameter.

It is not how parameters are described. For example, there is no need to say that a parameter is... a parameter.

+   * @param \Drupal\Core\Field\FieldDefinitionInterface $field_definition
+   *   The FeildDefintion service.

There are two typos.

Hi, I have updated the parameter comments.

@apaderno, could you please check in Drupal core code there also same defined

-   * @var EntityTypeManagerInterface
+   * Entity Type Manager service.
+   *
+   * @var \Drupal\Core\Entity\EntityTypeManagerInterface
    */

In English, there are rules about which words are written capitalized. On Entity Type Manager only the first word is correctly spelled.
There is a missing article, in the short description.

+   * @param string $plugin_id
+   *   The plugin_id for the formatter.
+   * @param mixed $plugin_definition
+   *   The plugin implementation definition.

It is redundant to say that the $plugin_id parameter is the plugin_id of the formatter, since that is repeating the parameter name.
The correct description for those parameters can be seen in constructors like PluginBase::__construct(), for example.

+   * @param string $label
+   *   The formatter label display setting.

It is sufficient to say The formatter label.

    * @param array $third_party_settings
-   * @param EntityTypeManagerInterface $entity_type_manager
+   *   Any third party settings.
+   * @param \Drupal\Core\Entity\EntityTypeManagerInterface $entity_type_manager
+   *   The Entity type manager service.

Any>/em> is not necessary.
Entity is misspelled, since it is not at the beginning of the sentence (contrary to The).
