Support new GitHub issue custom fields in GitHub integration

What is the challenge?

• In May 2026, GitHub released a new way to create issue fields: https://github.blog/changelog/2026-05-21-issue-fields-are-now-in-public-preview-for-all-organizations/. This new method of creating issue custom fields is not currently supported in the Aha! integration

What is the impact?

• Currently, only project custom fields are supported through the Aha! GitHub integration, and is the only workaround to connect custom field types using the integration

Describe your idea.

• Ensure that the new method of creating issue custom fields is supported in the Aha! GitHub integration
