Release 5.2.1 - Oauth scopes review

[david-ruiz-cko]

This release adds a comprehensive set of constants for all OAuth 2.0 scopes supported by the Checkout.com API, making it easier and safer to specify scopes without hardcoding strings. It also introduces documentation, usage examples, and unit tests for these constants, and updates the SDK version to reflect the new feature.

New OAuth Scopes Constants:

• Added OAuthScopes export in src/oauth-scopes.js, providing all documented and operational OAuth 2.0 scopes as constants, alphabetically ordered and frozen to prevent modification.
• Updated src/index.js to export OAuthScopes for use in client code.

Documentation and Usage Improvements:

• Extended the README.md with a new section explaining how to use the OAuthScopes constants and how TypeScript users can type their scope lists.

Testing and Reliability:

• Added a new test suite in test/oauth-scopes/oauth-scopes-unit.js to verify that all scope constants are correct, unique, alphabetically ordered, and immutable.
• Updated test/issuing/issuing-common.js to use the new OAuthScopes constants instead of hardcoded scope strings, and removed references to retired/invalid scopes.

Versioning:

• Bumped the package version to 5.2.0 in package.json to reflect the addition of the new feature.
