Fix the issues reported by phpcs

Finding coding standard issues as detailed in the issue summary. I will work on fixing them.

I have fixed all of the issues except for those relating to documentation. I have issued the MR against the 8.x-1.x branch.
Please review.

Hi sidharth_soman

I applied your MR and confirmed that it resolved the issues except for those related to documentation. Please see the screenshots attached.

For your review.
Thank you.

 function field_config_cardinality_form_alter(&$form, FormStateInterface $form_state, $form_id) {

What the report says is that for hook implementation, parameters are not described. In fact, the short description for a hook implementation and sole part of its documentation comment is totally different.

   if ($form_state->getValue('cardinality') === 'number' && $form_state->getValue('cardinality_number')) {
     $cardinality_config = $form_state->getValue('cardinality_number');
   }

The same holds true here.

 function field_config_cardinality_field_widget_multivalue_form_alter(&$elements, FormStateInterface $form_state, $context) {

Those @param tags are not necessary.

I would rather remove those comments, since they describe something that is already clear from the code.

Either the documentation comment is not empty or it is not added.
