Add or correct the documentation comments used for files/classes/functions/methods

+/**
+ * @file
+ * Module file.

The usual description is Hook implementations for the [module name] module. where [module name] is the module name shown in the .info.yml file.

I have uploaded the patch. Please review

It is Hook implementations for the Stripe Pay module.

See my previous comment.

Actually, let us rescope this issue. There are many documentation comments that need to be fixed.

The documentation comment for the .module file is missing. Furthermore, there are other documentation comments that are incomplete or need to be fixed. For example:

/**
 * Get currency codes available on the stripe
 */
function stripe_currency_codes()

It does not describe the return value. The verb used in the description needs to be declined on the third person singular.

/**
 * Price format
 */
function stripe_price_formats($currency_code, $currency_sign)

It does not describe the parameters nor the return value.

/**
* Log messages on the system
* @param  $log_type type of the error message
* @param  $message  message body
* @return
*/
function log_stripe_pay_messages($log_type, $message)

The documentation comment is not correctly formatted. The verb used in the description needs to be declined on the third person singular.

/**
* Plugin implementation of the 'stripe_payment' field type.
*
* @FieldType(
*   id = "stripe_payment",
*   label = @Translation("Stripe Payment"),
 *  category = @Translation("Stripe Payment"),
*   default_widget = "stripe_payment_default_widget",
*   default_formatter = "stripe_payment_default_formatter"
* )
*/
class StripePaymentFieldItem extends FieldItemBase implements FieldItemInterface {

The documentation comment is not correctly formatted.

Updated patch with the above mentioned changes.
