Code Review

This pull request correctly adds a minItems: 1 constraint to the tabs array in both v0.9 and v0.10 specifications, ensuring a Tabs component cannot be empty. My feedback focuses on the lack of accompanying tests for this change, which is required by the repository's contribution guidelines. Please add test cases that verify an empty tabs array fails validation for both specification versions.

This change correctly enforces that a Tabs component must have at least one tab. However, it is missing a corresponding test case for the v0.9 specification. To ensure this constraint is validated, please add a test case with a Tabs component that has an empty tabs array and is expected to fail validation.
