Update validation error object matching Ajv ErrorObject

[nazarhussain]

Description

While upgrading Ajv to version 8.1.0. Its observed that ErrorObject introduced a couple of changes. To keep the backend compatibility we introduced a wrapper to covert the error object.

https://github.com/LiskHQ/lisk-sdk/blob/c632e17a24e1a865fa6a14cb2147d24634e52f24/elements/lisk-validator/src/types.ts#L19-L22

We also have our own implementation of ErrorObject to single string conversion.

The Ajv in version 8.1.0 introduced ajv.errorText(errors) for the same purpose. We should move our implementation to this native function.

Motivation

The above mentioned changes will provide us following benefits;

1. Use consistent error object structure while debugging
2. Stay aligned with the validation library we are using
3. Easy to use third party libraries around ajv without any compatibility issues
4. We may in future start using ajv-errors to specify custom error messages inside schema declaration
5. We can also use ajv-i18n for internationlization of error messages

Acceptance Criteria

• The custom LiskErrorObject should be removed
• All the logic for converting one error format to other should be removed
• Use ajv.errorText to get single string conversion of validation errors

Additional Information

• Because it will introduce changes in the data structure for ErrorObject so to be considered as breaking change.
