[PAP][GraphQL] resetPassword mutation returns generic error

[magento-engcom-team]

While implementing resetPassword functionality into PWA, an engineer ran into a problem that resulted in this generic error response: Cannot set the customer's password. It took digging through the exception log to discover the provided password didn't meet the minimum password requirements, which was not in the error message.

<2020-08-11 19:59:26] report.ERROR: Cannot set the customer's password {"exception":"[object] (GraphQL\\Error\\Error(code: 0): Cannot set the customer's password at /app/vendor/webonyx/graphql-php/src/Error/Error.php:174, Magento\\Framework\\GraphQl\\Exception\\GraphQlInputException(code: 0): Cannot set the customer's password at /app/vendor/magento/module-customer-graph-ql/Model/Resolver/ResetPassword.php:121, Magento\\Framework\\Exception\\InputException(code: 0): Minimum of different classes of characters in password is 3. Classes of characters: Lower Case, Upper Case, Digits, Special Characters. at /app/vendor/magento/module-customer/Model/AccountManagement.php:764)"} [>

Repro Steps:

1. Execute requestPasswordResetEmail mutation and extract token from email
2. Execute resetPassword mutation with a weak password in newPassword field

Expected: Error is returned with language explaining password didn't meet specific requirements (message from exception log)
Actual: Cannot set the customer's password
